Impact of Ventricular Morphology on Myocardial Deformation in Patients with Single Ventricle

Abstract

unctionally single ventricle arrangements represent a heterogeneous group of anomalies sharing common feature which is functional single cardiac chamber. In most patients with functionally univentricular hearts (UVH) there are two morphologic ventricles, one of which is too small to sustain one of the circulations. In different series of congenital heart disease patients, cases of UVH represent about 1–2% of total congenital heart diseases. Two-dimensional speckle-tracking echocardiography has recently emerged as a novel technique for objective and quantitative evaluation of global and regional myocardial function, independent of the angle of myocardial insonation. The study included 47 patients with functional single ventricle whether they underwent cavopulmonary anastomosis or not. Referred for elective cardiac catheterization or follow up echocardiography in Ain Shams university hospitals, Cardiology department, from November 2017 to July 2018.
