Standardization of adult transthoracic echocardiography reporting in agreement with recent chamber quantification, diastolic function, and heart valve disease recommendations: an expert consensus document of the European Association of Cardiovascular Imaging.

Abstract: Aims This European Association Cardiovascular Imaging (EACVI) Expert Consensus document aims at defining the main quantitative information on cardiac structure and function that needs to be included in standard echocardiographic report following recent ASE/EACVI chamber quantification, diastolic function, and heart valve disease recommendations The document focuses on general reporting and specific pathological conditions such as heart failure, coronary artery and valvular heart disease, cardiomyopathies, and systemic diseases Methods and results Demographic data (age, body surface area, blood pressure, and heart rhythm and rate), type (vendor and model) of ultrasound system used and image quality need to be reported In addition, measurements should be normalized for body size Reference normal values, derived by ASE/EACVI recommendations, shall always be reported to differentiate normal from pathological conditions This Expert Consensus document suggests avoiding the surveillance of specific variable using different ultrasound techniques (eg in echo labs with high expertise in left ventricular ejection fraction by 3D and not by 2D echocardiography) The report should be also tailored in relation with different cardiac pathologies, quality of images, and needs of the caregivers Conclusion The conclusion should be concise reflecting the status of left ventricular structure and function, the presence of left atrial and/or aortic dilation, right ventricular dysfunction, and pulmonary hypertension, leading to an objective communication with the patient health caregiver Variation over time should be considered carefully, taking always into account the consistency of the parameters used for comparison

Echo-Doppler estimation of left ventricular filling pressure: results of the multicentre EACVI Euro-Filling study.

Abstract: Aims The present Euro-Filling report aimed at comparing the diagnostic accuracy of the 2009 and 2016 echocardiographic grading algorithms for predicting invasively measured left ventricular filling pressure (LVFP). Method and results A total of 159 patients who underwent simultaneous evaluation of echo estimates of LVFP and invasive measurements of LV end-diastolic pressure (LVEDP) were enrolled at nine EACVI centres. Thirty-nine (25%) patients had a reduced LV ejection fraction (<50%), 77 (64%) were in NYHA ≥ II, and 85 (53%) had coronary artery disease. Sixty-four (40%) patients had elevated LVEDP (≥15 mmHg). Taken individually, all echocardiographic Doppler estimates of LVFP (E/A, E/e', left atrial volume, tricuspid regurgitation jet velocity) were marginally correlated with LVEDP. By using the 2016 recommendations, 65% of patients with normal non-invasive estimate of LVFP had normal LVEDP, while 79% of those with elevated non-invasive LVFP had elevated invasive LVEDP. By using 2009 recommendations, 68% of the patients with normal non-invasive LVFP had normal LVEDP, while 55% of those with elevated non-invasive LVFP had elevated LVEDP. The 2016 recommendations (sensitivity 75%, specificity 74%, positive predictive value 39%, negative predictive value 93%, AUC 0.78) identified slightly better patients with elevated invasive LVEDP (≥ 15 mmHg) as compared with the 2009 recommendations (sensitivity 43%, specificity 75%, positive predictive value 49%, negative predictive value 71%, AUC 0.68). Conclusion The present Euro-Filling study demonstrates that the new 2016 recommendations for assessing LVFP non-invasively are fairly reliable and clinically useful, as well as superior to the 2009 recommendations in estimating invasive LVEDP.

Echocardiographic reference ranges for normal left ventricular 2D strain: results from the EACVI NORRE study

Abstract: Aims - To obtain the normal ranges for 2D echocardiographic (2DE) measurements of left ventricular (LV) strain from a large group of healthy volunteers accounting for age and gender. Methods and results - A total of 549 (mean age: 45.6 ± 13.3 years) healthy subjects were enrolled at 22 collaborating institutions of the Normal Reference Ranges for Echocardiography (NORRE) study. 2DE data sets have been analysed with a vendor-independent software package allowing homogeneous measurements irrespective of the echocardiographic equipment used to acquire the data sets. The lowest expected values of LV strains and twist calculated as ± 1.96 standard deviations from the mean were -16.7% in men and -17.8% in women for longitudinal strain, -22.3% and -23.6% for circumferential strain, 20.6% and 21.5% for radial strain, and 2.2 degrees and 1.9 degrees for twist, respectively. In multivariable analysis, longitudinal strain decreased with age whereas the opposite occurred with circumferential and radial strain. Male gender was associated with lower strain for longitudinal, circumferential, and radial strain. Inter-vendor differences were observed for circumferential and radial strain despite the use of vendor-independent software. Importantly, no intervendor differences were noted in longitudinal strain. Conclusion - The NORRE study provides contemporary, applicable 2D echocardiographic reference ranges for LV longitudinal, radial, and circumferential strain. Our data highlight the importance of age- and gender-specific reference values for LV strain.

Comprehensive multi-modality imaging approach in arrhythmogenic cardiomyopathy-an expert consensus document of the European Association of Cardiovascular Imaging.

Abstract: Arrhythmogenic cardiomyopathy (AC) is a progressive disease with high risk of life-threatening ventricular arrhythmias. A genetic mutation is found in up to 50-60% of probands, mostly affecting desmosomal genes. Diagnosis of AC is made by a combination of data from different modalities including imaging, electrocardiogram, Holter monitoring, family history, genetic testing, and tissue properties. Being a progressive cardiomyopathy, repeated cardiac imaging is needed in AC patients. Repeated imaging is important also for risk assessment of ventricular arrhythmias. This expert consensus document gives clinical recommendations for how to use multi-modality imaging in the different aspects of AC disease, including diagnosis, family screening, follow-up, risk assessment, and differential diagnosis.

2D and 3D strain for detection of subclinical anthracycline cardiotoxicity in breast cancer patients: a balance with feasibility.

Abstract: Aims 2D echocardiography is limited for identifying chemotherapy-related cardiotoxicity. This study compared standard echo, 2D, and 3D speckle tracking echocardiography (STE) for detection of subclinical anthracycline (ANT) cardiotoxicity in breast cancer patients. Methods and results One-hundred consecutive breast cancer patients free of cardiac symptoms were treated by multiple protocols including ANT and cyclophosphamide and/or 5-fluorouracil for 3-4 cycles. Both before and after treatment, patients underwent standard echo, 2D STE-derived left ventricular (LV) global longitudinal strain (GLS), 3D volumetric echo and 3D STE with measurements of GLS, global circumferential strain (GCS), global area strain (GAS), and global radial strain (GRS). The follow-up period from the beginning of cancer therapy was 129 ± 18 days. All patients completed the chemotherapy cycles, without experiencing symptoms/signs of heart failure. 2D ejection fraction (EF) was not significantly changed after treatment, whereas E/e' ratio was higher than baseline (from 6.9 ± 2.2 to 7.3 ± 2.1, P = 0.006). 2D GLS was reduced after treatment (from -22.2 ± 2.3% to - 20.1 ± 6.6%, P = 0.004). 3D derived LV end-systolic volume was increased (P < 0.01) and 3D EF (from 62.4 ± 6.5% to 60.3 ± 7.3%, P < 0.01), 3D GLS (P < 0.001) GRS (P < 0.002), GCS, and GAS (both P < 0.0001) were reduced after ANT. Post-ANT 2D GLS was feasible in 90%, 3D EF in 66%, and 3D STE in 60% of patients. Conclusions Our study demonstrates potential superiority but also suboptimal feasibility of 3D EF and 3D strain in diagnosing subclinical ANT cardiotoxicity in breast cancer patients. 2D GLS is superior to standard echo and presents a good feasibility. E/e' ratio also offers advantages in revealing cardiotoxicity.

Stress echo 2020: the international stress echo study in ischemic and non-ischemic heart disease

Abstract: Stress echocardiography (SE) has an established role in evidence-based guidelines, but recently its breadth and variety of applications have extended well beyond coronary artery disease (CAD). We lack a prospective research study of SE applications, in and beyond CAD, also considering a variety of signs in addition to regional wall motion abnormalities. In a prospective, multicenter, international, observational study design, > 100 certified high-volume SE labs (initially from Italy, Brazil, Hungary, and Serbia) will be networked with an organized system of clinical, laboratory and imaging data collection at the time of physical or pharmacological SE, with structured follow-up information. The study is endorsed by the Italian Society of Cardiovascular Echography and organized in 10 subprojects focusing on: contractile reserve for prediction of cardiac resynchronization or medical therapy response; stress B-lines in heart failure; hypertrophic cardiomyopathy; heart failure with preserved ejection fraction; mitral regurgitation after either transcatheter or surgical aortic valve replacement; outdoor SE in extreme physiology; right ventricular contractile reserve in repaired Tetralogy of Fallot; suspected or initial pulmonary arterial hypertension; coronary flow velocity, left ventricular elastance reserve and B-lines in known or suspected CAD; identification of subclinical familial disease in genotype-positive, phenotype- negative healthy relatives of inherited disease (such as hypertrophic cardiomyopathy). We expect to recruit about 10,000 patients over a 5-year period (2016-2020), with sample sizes ranging from 5,000 for coronary flow velocity/ left ventricular elastance/ B-lines in CAD to around 250 for hypertrophic cardiomyopathy or repaired Tetralogy of Fallot. This data-base will allow to investigate technical questions such as feasibility and reproducibility of various SE parameters and to assess their prognostic value in different clinical scenarios. The study will create the cultural, informatic and scientific infrastructure connecting high-volume, accredited SE labs, sharing common criteria of indication, execution, reporting and image storage of SE to obtain original safety, feasibility, and outcome data in evidence-poor diagnostic fields, also outside the established core application of SE in CAD based on regional wall motion abnormalities. The study will standardize procedures, validate emerging signs, and integrate the new information with established knowledge, helping to build a next-generation SE lab without inner walls.

Multimodality imaging in restrictive cardiomyopathies: an EACVI expert consensus document: In collaboration with the 'Working Group on myocardial and pericardial diseases' of the European Society of Cardiology Endorsed by the Indian Academy of Echocardiography

Abstract: Restrictive cardiomyopathies (RCMs) are a diverse group of myocardial diseases with a wide range of aetiologies, including familial, genetic and acquired diseases and ranging from very rare to relatively frequent cardiac disorders. In all these diseases, imaging techniques play a central role. Advanced imaging techniques provide important novel data on the diagnostic and prognostic assessment of RCMs. This EACVI consensus document provides comprehensive information for the appropriateness of all non-invasive imaging techniques for the diagnosis, prognostic evaluation, and management of patients with RCM.

Non-invasive cardiovascular imaging for evaluating subclinical target organ damage in hypertensive patients: A consensus paper from the European Association of Cardiovascular Imaging (EACVI), the European Society of Cardiology Council on Hypertension, and the European Society of Hypertension (ESH).

Abstract: Arterial hypertension (HTN) accounts for the largest amount of attributable cardiovascular (CV) mortality worldwide, and risk stratification in hypertensive patients is of crucial importance to manage treatment and prevent adverse events. Asymptomatic involvement of different organs in patients affected by HTN represents an independent determinant of CV risk and the identification of target organ damage (TOD) is recommended to further reclassify patients' risk. Non-invasive CV imaging is progressively being used and continues to provide new technological opportunities to TOD evaluation at early stage. The aim of this article is to provide the community of cardiology with an update on appropriate and justified use of non-invasive imaging tests in the growing population of hypertensive patients.

Normal reference values of multilayer longitudinal strain according to age decades in a healthy population: A single-centre experience.

Abstract: Aims Recent advancements in echocardiographic technology allow to analyse myocardial strain in multiple layers. Little is known about the impact of age on layer-specific longitudinal strain in healthy subjects. The aim of this study was to analyse the influence of age on multilayer longitudinal strain and establish normal reference values of layer-specific strain according to age decades in a healthy population referring to our echo laboratory using 2D speckle-tracking echocardiography with layer-specific software. Methods and results Two-hundred sixty-six healthy, consecutive subjects (mean age = 39.2 ± 17.5 years, women/men = 137/129), free of cardiovascular risk factors, were enrolled. Subjects were divided according to six age decades: 10-19, 20-29, 30-39, 40-49, 50-59, >60 years. All subjects underwent a complete echo Doppler examination including quantitation of 2D global longitudinal strain (GLS). Subendocardial longitudinal strain (LSsubendo), subepicardial longitudinal strain (LSsubepi), and strain gradient (LSsubendo - LSsubepi) were also determined. GLS (P < 0.001), LSsubendo, and LSsubepi (both P < 0.0001) were all progressively reduced with increasing age decades, but post hoc intra-group analyses demonstrated that the decline of GLS, LSsubendo, and LSsubepi was significant in the decades 50-60 and ≥60 years. In separate multiple linear regression analyses, the effect of age on GLS, LSsubendo, and LSsubepi remained significant even after adjusting for clinical and echocardiographic confounders. Strain gradient remained unchanged in age decades. Conclusion Ageing shows an independent effect on GLS, LSsubendo, and, particularly on, LSsubepi. Our data also provide normal reference values of layer-specific longitudinal strain for age decades.

Cardiac damage in athlete's heart: When the "supernormal" heart fails!

Abstract: Intense exercise may cause heart remodeling to compensate increases in blood pressure or volume by increasing muscle mass. Cardiac changes do not involve only the left ventricle, but all heart chambers. Physiological cardiac modeling in athletes is associated with normal or enhanced cardiac function, but recent studies have documented decrements in left ventricular function during intense exercise and the release of cardiac markers of necrosis in athlete's blood of uncertain significance. Furthermore, cardiac remodeling may predispose athletes to heart disease and result in electrical remodeling, responsible for arrhythmias. Athlete's heart is a physiological condition and does not require a specific treatment. In some conditions, it is important to differentiate the physiological adaptations from pathological conditions, such as hypertrophic cardiomyopathy, arrhythmogenic dysplasia of the right ventricle, and non-compaction myocardium, for the greater risk of sudden cardiac death of these conditions. Moreover, some drugs and performance-enhancing drugs can cause structural alterations and arrhythmias, therefore, their use should be excluded.

Expert Review on the Prognostic Role of Echocardiography after Acute Myocardial Infarction.

Abstract: Acute myocardial infarction (AMI) remains a leading cause of morbidity and mortality worldwide, placing a major economic and resource burden on public health systems. During hospitalization, all AMI patients should be evaluated with transthoracic echocardiography, a noninvasive, low-cost, and easily available bedside imaging tool that allows the detection of myocardial walls involved in the ischemic process, damage extent, functional consequences, and mechanical complications. Moreover, and more importantly, transthoracic echocardiography can provide information on short- and long-term outcomes after AMI. The purpose of this review is to clarify the role of standard and advanced echocardiographic parameters for an early identification of patients at high risk for developing adverse events and mortality after AMI. Standard echocardiography (in particular left ventricular ejection fraction, wall motion score index, and diastolic measurements including E velocity deceleration time and E/e′ ratio) proposes powerful parameters for risk stratification after AMI. Advanced echocardiographic technologies, in particular speckle-tracking–derived longitudinal strain, coronary flow velocity reserve, and myocardial contrast echocardiography (contrast defect index), can provide additional prognostic value beyond standard techniques. Therefore, echocardiography plays a fundamental role in predicting short- and long-term prognosis, and a more accurate risk stratification of patients may be useful to drive therapy and follow-up after AMI. Accordingly, a comprehensive echocardiography-based algorithm would be welcome for an early stratification of cardiovascular risk in patients experiencing AMI.

Meta-Analysis of Effect of Body Mass Index on Outcomes After Transcatheter Aortic Valve Implantation

Abstract: Controversial data exist regarding the impact of body mass index (BMI) on TAVI outcomes. Thirteen TAVI studies were included and analyzed for the incidence of procedural complications, 30-day, and long-term all-cause mortality. Three comparisons were executed: (1) underweight versus normal weight, (2) overweight versus normal weight, and (3) obese versus normal weight patients. Underweight patients (BMI 30 kg/m2) had similar 30-day all-cause mortality rates compared with the normal weight category, whereas they displayed a significant better survival at long-term (hazard ratio 0.79, 95% CI 0.67 to 0.93, p = 0.004). Procedural complications did not differ between obese and normal body weight patients. In conclusion, a low BMI is linked to a significantly worse prognosis after TAVI. Therefore, BMI represents an important and handily tool that might be used in the risk prediction of patients to be addressed for TAVI.

Appropriateness criteria for the use of cardiovascular imaging in heart valve disease in adults: a European Association of Cardiovascular Imaging report of literature review and current practice

Abstract: Heart valve disease is common and a major indication for imaging. Echocardiography is the first-line imaging technique for diagnosis, assessment, and serial surveillance. However, other modalities, notably cardiac magnetic resonance imaging and computerized tomography, are used if echocardiographic imaging is suboptimal or to obtain complementary information, particularly to aid risk assessment in individual patients. This review is a summary of current evidence for state-of-the-art clinical practice to inform appropriateness criteria for heart valve disease. It is divided according to common clinical scenarios: detection of valve disease, assessment of the valve and other cardiac structures, risk assessment, screening, and intervention.

Left ventricular hypertrophy or storage disease? the incremental value of speckle tracking strain bull's-eye

Abstract: Left ventricular hypertrophy (LVH) develops in response to a variety of physical, genetic, and biochemical stimuli and represents the early stage of ventricular remodeling. In patients with LVH, subclinical left ventricular (LV) dysfunction despite normal ejection fraction (EF) may be present before the onset of symptoms, which portends a dismal prognosis. Strain measurement with two-dimensional speckle tracking echocardiography (STE) represents a highly reproducible and accurate alternative to LVEF determination. The present review focuses on current available evidence that supports the incremental value of STE in the diagnostic and prognostic workup of LVH. When assessing the components of LV contraction, STE has an incremental value in differentiating between primary and secondary LVH and in the differential diagnosis with storage diseases. In addition, STE provides unique information for the stratification of patients with LVH, enabling to detect intrinsic myocardial dysfunction before LVEF reduction.

Validation of Left Atrial Volume Estimation by Left Atrial Diameter from the Parasternal Long-Axis View.

Abstract: Background Measurement of left atrial (LA) volume (LAV) is recommended for quantification of LA size. Only LA anteroposterior diameter (LAd) is available in a number of large cohorts, trials, or registries. The aim of this study was to evaluate whether LAV may be reasonably estimated from LAd. Methods One hundred forty consecutive patients referred to our outpatient clinics were prospectively enrolled to measure LAd from the long-axis view on two-dimensional echocardiography. LA orthogonal dimensions were also taken from apical four- and two-chamber views. LAV was measured using the Simpson, area-length, and ellipsoid (LAV e ) methods. The first 70 patients were the learning series and the last 70 the testing series (TeS). In the learning series, best-fitting regression analysis of LAV-LAd was run using all LAV methods, and the highest values of F were chosen among the regression equations. In the TeS, the best-fitting regressions were used to estimate LAV from LAd. Results In the learning series, the best-fitting regression was linear for the Spearman method ( r 2 = 0.62, F = 111.85, P = .0001) and area-length method ( r 2 = 0.62, F = 112.24, P = .0001) and powered for the LAV e method ( r 2 = 0.81, F = 288.41, P = .0001). In the TeS, the r 2 value for LAV prediction was substantially better using the LAV e method ( r 2 = 0.89) than the Simpson ( r 2 = 0.72) or area-length ( r 2 = 0.70) method, as was the intraclass correlation (ρ = 0.96 vs ρ = 0.89 and ρ = 0.89, respectively). In the TeS, the sensitivity and specificity of LA dilatation by the estimated LAV e method were 87% and 90%, respectively. Conclusions LAV can be estimated from LAd using a nonlinear equation with an elliptical model. The proposed method may be used in retrospective analysis of existing data sets in which determination of LAV was not programmed.

Effects of long-term combined treatment with somatostatin analogues and pegvisomant on cardiac structure and performance in acromegaly.

Abstract: To date, no data are available on the effects of long-term combined treatment with somatostatin analogues (SA) and pegvisomant (PEG) on cardiovascular complications in acromegaly. The current study aimed at investigating the effects of long-term SA + PEG on cardiac structure and performance. Thirty-six patients (14 M, 22 F, aged 52.3 ± 10.2 years) entered this study. Weight, BMI, systolic (SBP) and diastolic (DBP) blood pressure, IGF-I, fasting glucose (FG), fasting insulin (FI), HOMA-IR, HbA1c, and lipids were evaluated at baseline (T0), after long-term (median 36 months) SA (T1), after 12 (T12) and 60 (T60) months of SA + PEG, and at last follow-up (LFU, median 78 months). At each time point, all patients underwent echocardiography. At T1, induced a slight but not significant decrease in IGF-I (p = 0.077), whereas FI (p = 0.004), HOMA-IR (p = 0.013), ejection fraction (EF, p = 0.013), early (E) to late (A) ventricular filling velocities (E/A, p = 0.001), and isovolumetric relaxation time (IVRT, p = 0.000) significantly improved. At T12, IGF-I (p = 0.000) significantly reduced compared to T0, and FI (p = 0.001), HOMA-IR (p = 0.000), LVMI (p = 0.000), and E/A (p = 0.006) further improved compared to T1. At T60, FI (p = 0.027), HOMA-IR (p = 0.049), and E/A (p = 0.005) significantly improved as compared to T1. At LFU IGF-I normalized in 83.3 %, FI (p = 0.000), HOMA-IR (p = 0.000), LVMi (p = 0.000), and E/A (p = 0.005) further improved as compared to T1. PEG dose significantly correlated with LVMi at T12 (r = 0.575, p = 0.000) and T60 (r = 0.403, p = 0.037). Long-term PEG addition to SA improves cardiac structure and performance, particularly diastolic dysfunction, in acromegalic patients resistant to SA.

L’ecocardiografia speckle tracking: roadmap per la misurazione e l’utilizzo clinico

Abstract: Speckle tracking echocardiography (STE) has recently emerged as a quantitative technique to accurately estimate myocardial function. By the analysis of the motion of speckles in the two-dimensional ultrasonic image, this technique allows a non-Doppler angle-independent objective analysis of myocardial deformation, with the possibility to quantify thickening, shortening and rotation dynamics of cardiac function. Since this technique does not require Doppler imaging, the analysis is relatively angle-independent and is marginally affected by cardiac in-plane motion artifacts. Data regarding feasibility, reproducibility and diagnostic accuracy appear to be optimal in several clinical contexts. This review describes the fundamental concepts of deformation imaging, explains how to obtain myocardial deformation measurements in clinical practice and highlights current clinical applications of STE. In addition, in relation with the recent extension of STE to three-dimensional echocardiography with the potential for a more comprehensive analysis of global and segmental myocardial function, a window is also opened on the perspectives of three-dimensional STE.

Acute and Chronic Response to Exercise in Athletes: The "Supernormal Heart".

Abstract: During last decades, most studies have examined the exercise-induced remodeling defined as “athlete’s heart”. During exercise, there is an increased cardiac output that causes morphological, functional, and electrical modification of the cardiac chambers. The cardiac remodeling depends also on the type of training, age, sex, ethnicity, genetic factors, and body size. The two main categories of exercise, endurance and strength, determine different effects on the cardiac remodeling. Even if most sport comprise both strength and endurance exercise, determining different scenarios of cardiac adaptation to the exercise. The aim of this paper is to assemble the current knowledge about physiologic and pathophysiologic response of both the left and the right heart in highly trained athletes.

Protocol update and preliminary results of EACVI/HFA Cardiac Oncology Toxicity (COT) Registry of the European Society of Cardiology

Abstract: Aims European Association of Cardiovascular Imaging/Heart Failure Association Cardiac Oncology Toxicity Registry was launched in October 2014 as a European Society of Cardiology multicentre registry of breast cancer patients referred to imaging laboratories for routine surveillance, suspected, or confirmed anticancer drug-related cardiotoxicity (ADRC). After a pilot phase (1 year recruitment and 1 year follow-up), some changes have been made to the protocol (version 1.0) and electronic case report form. Methods and results Main changes of the version 2.0 concerned exclusion criteria, registry duration, and clarification of the population characteristics. Breast cancer radiotherapy has been removed as an exclusion criterion, which involves now only history of a pre-chemotherapy left ventricular dysfunction. The period for long-term registry recruitment has been reduced (December 2017), but the target study population was extended to 3000 patients. The characteristics of the population are now better defined: patients seen in an imaging lab, which will include patients undergoing chemotherapy with associated targeted therapy or no targeted therapy, at increased risk of ADRC. In total, 1294 breast cancer patients have been enrolled, and 783 case report forms locked from October 2014 to November 2016. Of these, 481 (61.4%) were seen at first evaluation and 302 (38.6%) while on oncologic treatment with anticancer drugs. Fifty-two patients (17.2%) were not in targeted therapies, 191 (63.3%) were ongoing targeted therapy, and 59 (19.5%) had completed it. Twenty-three (2.9%) patients had a suspected diagnosis and 35 (4.5%) a confirmed diagnosis of ADRC. Arterial hypertension was the most prevalent cardiovascular risk factor (29.2%) followed by diabetes (6.1%). Previous history of heart failure accounted for 0.5%, whereas previous cardiac disease was identified in 6.3% of population. Conclusion The changes of the original protocol of the COT Registry and first update allow a first glance to the panorama of cardiovascular characteristics of breast cancer patients enrolled.

Rational and design of EuroCRT: an international observational study on multi-modality imaging and cardiac resynchronization therapy.

Abstract: Aims: Assessment of left ventricular (LV) volumes and ejection fraction (LVEF) with cardiac imaging is important in the selection of patients for cardiac resynchronization therapy (CRT). Several observational studies have explored the role of imaging-derived LV dyssynchrony parameters to predict the response to CRT, but have yielded inconsistent results, precluding the inclusion of imaging-derived LV dyssynchrony parameters in current guidelines for selection of patients for CRT. Methods: The EuroCRT is a large European multicentre prospective observational study led by the European Association of Cardiovascular Imaging. We aim to explore if combing the value of cardiac magnetic resonance (CMR) and echocardiography could be beneficial for selecting heart failure patients for CRT in terms of improvement in long-term survival, clinical symptoms, LV function, and volumes. Speckle tracking echocardiography will be used to assess LV dyssynchrony and wasted cardiac work whereas myocardial scar will be assessed with late gadolinium contrast enhanced CMR. All data will be measured in core laboratories. The study will be conducted in European centres with known expertise in both CRT and multimodality cardiac imaging.

Myocardial deformation in pediatric patients with mucopolysaccharidoses: A two-dimensional speckle tracking echocardiography study.

Abstract: BACKGROUND Mucopolysaccharidoses (MPS) are inherited lysosomal storage disorders caused by deficiency of required glycosaminoglycans breakdown enzymes, inducing cardiac involvement. Little is known about myocardial deformation involvement in MPS. Our aim was to assess biventricular structure and function in asymptomatic children with MPS using standard echo Doppler and 2D speckle tracking (STE). METHODS Fifteen MPS children (one type I, six type II, three type III A, one III B, three IV A, one VI), asymptomatic for cardiac symptoms, and 15 age and sex-matched healthy controls underwent echo Doppler and STE. Left ventricular (LV) wall thicknesses, diameters, and mass were normalized by z-score. LV global longitudinal strain (GLS), global circumferential strain (GCS), global radial strain (GRS) at papillary muscles, LV twisting, and right ventricular (RV) GLS were measured. RESULTS The two groups were comparable for body mass index, heart rate, and blood pressure. LV mass index and relative wall thickness were higher in MPS. Ejection fraction (EF), and s' velocity did not differ between the two groups. E/A ratio was lower and E/e' higher in MPS. Tricuspid annular plane systolic excursion, RV s' and e' were lower in MPS. LV GLS did not differ between the two groups, but GCS (P=.014), GRS (P=.023), twisting (P=.012), and RV GLS (P<.001) were lower in the MPS group. CONCLUSIONS LV strain abnormalities are detectable in MPS pediatric patients, independently of MPS type, when EF is still normal. RV GLS is also involved consensually with TAPSE reduction. STE can be useful for detection of subclinical myocardial damage in MPS.

Identification of the main determinants of abdominal aorta size: a screening by Pocket Size Imaging Device

Abstract: Ultrasound exam as a screening test for abdominal aorta (AA) can visualize the aorta in 99% of patients and has a sensitivity and specificity approaching 100% in screening settings for aortic aneurysm. Pocket Size Imaging Device (PSID) has a potential value as a screening tool, because of its possible use in several clinical settings. Our aim was to assess the impact of demographics and cardiovascular (CV) risk factors on AA size by using PSID in an outpatient screening. Consecutive patients, referring for a CV assessment in a 6 months period, were screened. AA was visualized by subcostal view in longitudinal and transverse plans in order to determine the greatest anterior-posterior diameter. After excluding 5 patients with AA aneurysm, 508 outpatients were enrolled. All patients underwent a sequential assessment including clinical history with collection of CV risk factors, physical examination, PSID exam and standard Doppler echoc exam using a 2.5 transducer with harmonic capability, both by expert ultrasound operators, during the same morning. Standard echocardiography operators were blinded on PSID exam and viceversa. Diagnostic accuracy of AA size by PSID was tested successfully with standard echo machine in a subgroup (n = 102) (rho = 0.966, p < 0.0001). AA diameter was larger in men than in women and in ≥50 -years old subjects than in those <50 -years old (both p < 0.0001). AA was larger in patients with coronary artery disease (CAD) (p < 0.0001). By a multivariate model, male sex (p < 0.0001), age and body mass index (both p < 0.0001), CAD (p < 0.01) and heart rate (p = 0.018) were independent predictors of AA size (cumulative R 2 = 0.184, p < 0.0001). PSID is a reliable tool for the screening of determinants of AA size. AA diameter is greater in men and strongly influenced by aging and overweight. CAD may be also associated to increased AA diameter.

Association Between Elevated Pulse Pressure and High Resting Coronary Blood Flow Velocity in Patients With Angiographically Normal Epicardial Coronary Arteries

Recommendations on the use of echocardiography in adult hypertension: a report from the European Association of Cardiovascular Imaging (EACVI) and the American Society of Echocardiography (ASE)

Abstract: Hypertension remains a major contributor to the global burden of disease. The measurement of blood pressure continues to have pitfalls related to both physiological aspects and acute variation. As the left ventricle (LV) remains one of the main target organs of hypertension, and echocardiographic measures of structure and function carry prognostic information in this setting, the development of a consensus position on the use of echocardiography in this setting is important. Recent developments in the assessment of LV hypertrophy and LV systolic and diastolic function have prompted the preparation of this document. The focus of this work is on the cardiovascular responses to hypertension rather than the diagnosis of secondary hypertension. Sections address the pathophysiology of the cardiac and vascular responses to hypertension, measurement of LV mass, geometry, and function, as well as effects of treatment.

The benefit of angiotensin AT1 receptor blockers for early treatment of hypertensive patients.

Abstract: ESC guidelines for management of arterial hypertension allow one to choose among five classes of antihypertensive drugs indiscriminately. They are based on the principle that in the management of hypertensive patients, it is fundamental to reduce blood pressure (BP), independently of the utilized drug. However, it has been demonstrated that the renin-angiotensin system (RAS) plays a relevant role in the hypertensive-derived development and progression of organ damage. Thus, antihypertensive drugs interfering with the RAS should be preferred in preventing and reducing target organ damage. The availability of two classes of drugs, ACE-inhibitors and angiotensin AT1 receptor blockers (ARBs), both interfering with the RAS, makes the choice between them difficult. Both pharmacological strategies offer an effective BP control, and a substantial improvement of prognosis in different associated pathologies. Regarding cardiovascular prevention, ACE-inhibitors have an extensive scientific literature regarding utility in high-risk patients. Nevertheless, there is evidence to support the concept that in the early phases of organ tissue damage, the RAS is activated, but the ACE pathway producing angiotensin II is not always employed. Accordingly, ACE-inhibitors appear to be less effective, whereas ARBs have a greater beneficial action in the initial stages of atherosclerotic disease. Moreover, patients undergoing ARBs therapy show a substantially lower risk of therapy discontinuation when compared to those treated with ACE-inhibitors, because of a better tolerability. In conclusion, ACE-inhibitors should be used in patients who have already developed organ damage, but tolerate this drug well, while ARBs should be the first choice in naive hypertensive patients without organ damage or at the initial stages of disease.
