Evaluation of Ventricular Filling Pressures and Ventricular Function by Doppler Echocardiography in Patients with Functional Single Ventricle: Correlation with Simultaneous Cardiac Catheterization

Background Elevated ventricular filling pressure is a marker of diastolic dysfunction and a known risk factor for failure of single-ventricle surgical palliation. Doppler echocardiography has been shown valuable in identifying patients with elevated ventricular end-diastolic pressure (VEDP) in other settings, but its utility in evaluating pediatric patients with single ventricle is unclear. The aim of this study was to compare Doppler parameters...
