Assessment of Dyssynchronous Wall Motion During Acute Myocardial Ischemia Using Velocity Vector Imaging
Kasumi Masuda,Toshihiko Asanuma,Asuka Taniguchi,Ayumi Uranishi,Fuminobu Ishikura,Shintaro Beppu +5 more
TL;DR: The assessment of VVI at MVO permits easy detection of dyssynchronous wall motion during acute myocardial ischemia that cannot be diagnosed by conventional measurement of systolic wall thickness and suggests the size of the risk area.

Early predictors of cardiac decompensation in experimental volume overload.

TL;DR: While early morphologic responses of LV walls to ACF correlated well with strain-dependent differences in late mortality, other functional changes showed no predictive effects, and close monitoring of early changes in cardiac geometry might be helpful to further improve risk stratification in humans with volume overload cardiopathies.

Non-invasive assessment of the haemodynamic significance of coronary stenosis using fusion of cardiac computed tomography and 3D echocardiography
Francesco Maffessanti,Amit R. Patel,Mita Patel,James Walter,Anuj Mediratta,Diego Medvedofsky,Nadjia Kachenoura,Nadjia Kachenoura,Roberto M. Lang,Victor Mor-Avi +9 more
TL;DR: In this feasibility study, resting strain showed good agreement with stress perfusion, indicating that it may be potentially used to assess haemodynamic impact of coronary stenosis, as an alternative to stress testing that entails additional radiation exposure.

Fusion of Three-Dimensional Echocardiographic Regional Myocardial Strain With Cardiac Computed Tomography for Noninvasive Evaluation of the Hemodynamic Impact of Coronary Stenosis in Patients With Chest Pain
Victor Mor-Avi,Mita Patel,Francesco Maffessanti,Francesco Maffessanti,Amita Singh,Diego Medvedofsky,S. Javed Zaidi,S. Javed Zaidi,Anuj Mediratta,Akhil Narang,Noreen Nazir,Nadjia Kachenoura,Roberto M. Lang,Amit R. Patel +13 more
TL;DR: Fusion of CTCA and 3D echocardiography–derived resting myocardial strain provides combined displays, which may be useful in determination of the hemodynamic or functional impact of coronary abnormalities, without additional ionizing radiation or stress testing.
Journal ArticleDOI
Postsystolic thickening detected by Doppler myocardial imaging: a marker of viability or ischemia in patients with myocardial infarction.
TL;DR: This work has shown that postsystolic thickening of ischemic myocardial segments has been reported to account for the characteristic heterogeneity or regional asynchrony of myocardIAL wall motion during acute ischemia, but the mechanism behind this change is still unclear.

Statistical methods for assessing agreement between two methods of clinical measurement.
TL;DR: An alternative approach, based on graphical techniques and simple calculations, is described, together with the relation between this analysis and the assessment of repeatability.

Myocardial Strain by Doppler Echocardiography Validation of a New Method to Quantify Regional Myocardial Function
TL;DR: Myocardial strain by Doppler echocardiography may represent a new, powerful method for quantifying regional myocardial function and is less influenced by tethering effects than Dopplers tissue imaging.

Real-time strain rate imaging of the left ventricle by ultrasound
TL;DR: In the healthy hearts, a spatially homogeneous distribution of the strain rate was found and all the infarcted areas in this study showed up as hypokinetic or akinetic, demonstrating that this method may be used for imaging of regional dysfunction.

TL;DR: The concomitant enhancement of the myocardial Doppler signal after an intravenous injection of a transpulmonary echocardiographic contrast agent could permit the noninvasive assessment of regional myocardIAL perfusion.
