Comparison of Echocardiographic and Pressure–volume Loop Indices of Systolic Function in Patients with Single Ventricle Physiology: A Preliminary Report

摘要

BackgroundDifferences in ventricular geometry and physiology of patients with single ventricle anatomy complicate the application of traditional, noninvasive measurements of systolic function. We compared noninvasive measures of ventricular systolic function in single ventricle patients with invasive measures to evaluate their validity in this population.
