Changes in myocardial function and hemodynamics after ligation of the ductus arteriosus in preterm infants.
TLDR
After PDA ligation, LV output and MPI decrease, due primarily to a decrease in LV preload, although LV contractility and diastolic function do not change, however, the changes in LV MPI after ligation also reflect an acute deterioration followed by an improvement in global cardiac function.About:

Failure of Ductus Arteriosus Closure Is Associated With Increased Mortality in Preterm Infants
Shahab Noori,Michael McCoy,Philippe Friedlich,Brianna C. Bright,Brianna C. Bright,Venugopal Gottipati,Istvan Seri,Kris C. Sekar +7 more
TL;DR: Failure of ductal closure is associated with an increase in mortality in very preterm infants, and the hazard for death in neonates with a persistent ductus was eightfold higher than in those with a closed ductus.

The Role of Patent Ductus Arteriosus Ligation in Bronchopulmonary Dysplasia: Reexamining a Randomized Controlled Trial
TL;DR: Prophylactic ligation, while eliminating the PDA, increases the risk for BPD.
Journal ArticleDOI
Use of targeted neonatal echocardiography to prevent postoperative cardiorespiratory instability after patent ductus arteriosus ligation.
TL;DR: Administration of milrinone to neonates with low cardiac output may lead to improved postoperative stability, and TnECHO facilitates early detection of infants at greatest risk for subsequent cardiorespiratory deterioration.
Journal ArticleDOI
Postoperative cardiorespiratory instability following ligation of the preterm ductus arteriosus is related to early need for intervention.
TL;DR: Surgical ligation of the ductus arteriosus in preterm infants less than 28 days old is associated with oxygenation difficulties, decreased systolic arterial pressure and an increased need for cardiotropic support in the initial 24 postoperative hours, suggesting the need to prospectively characterize perioperative cardiovascular physiology and identify predictive factors of clinical deterioration.
Journal ArticleDOI
Patent ductus arteriosus ligation is associated with impaired left ventricular systolic performance in premature infants weighing less than 1000 g
TL;DR: In this paper, the effect of patent ductus arteriosus ligation on myocardial performance in preterm infants was investigated and the authors found that infants weighing 1000 g or less had a higher rate of low fractional shortening and increased need for cardiotropes and demonstrated a trend toward an impaired stress-velocity relationship.

New index of combined systolic and diastolic myocardial performance: a simple and reproducible measure of cardiac function--a study in normals and dilated cardiomyopathy
Chuwa Tei,Lieng H. Ling,David O. Hodge,Kent R. Bailey,Jae K. Oh,R J Rodeheffer,Abdul J. Tajik,James B. Seward +7 more
TL;DR: (ICT+IRT)/ET is a conceptually new, simple and reproducible Doppler index of combined systolic and diastolic myocardial performance in patients with primarymyocardial systols dysfunction and was easily measured, reproducible, and had a narrow range in normals.

Noninvasive Doppler-derived myocardial performance index: Correlation with simultaneous measurements of cardiac catheterization measurements
TL;DR: This study documents that a simple, easily recordable, noninvasive Doppler index of myocardial performance correlates with invasive measurement of left ventricular systolic and diastolic function and appears to be a promisingnoninvasive measurement of overall cardiac function.

TL;DR: In healthy children, parameters of cardiac growth, most notably left ventricular end-diastolic dimension, have the most significant correlation with the majority of DTI velocities, whereas sex, heart rate, and other echocardiographic parameters demonstrated minimal or no correlation.

Tei-index in patients with mild-to-moderate congestive heart failure.
TL;DR: The Tei-Index is a sensitive indicator of overall cardiac dysfunction in patients with mild-to-moderate congestive heart failure and may be used in the work-up of patients with suspected cardiac dysfunction.

Nongeometric Quantitative Assessment of Right and Left Ventricular Function: Myocardial Performance Index in Normal Children and Patients with Ebstein Anomaly
TL;DR: The myocardial performance index quantitatively reflects ventricular performance in patients with complex ventricular geometry (ie, Ebstein anomaly) and in the absence of a geometric solution, this nongeometric index is particularly appealing for the assessment of RV or LV performance.
