Comparative Study between 3D Echocardiography Right Ventricular -Volumes and Functions- and Invasive RV Quantification in Children with Valvular Pulmonary Stenosis Pre and Post Balloon

Abstract

ongenital heart malformations are the most frequent of all major birth defects, with an estimated prevalence at birth of approximately 8-10 cases per 1000 births. Amongst congenital heart disease, pulmonary valve stenosis (PS) accounts for 10% of congenital heart diseases and is accompanied in approximately 20% of congenital heart disease cases. Echocardiographic evaluation of right ventricular (RV) function is a challenge due to the complex anatomy of the RV. Several transthoracic echocardiographic methods have been suggested for the quantification of RV function.
