Noninvasive Estimation of Ventricular Filling Pressures in Patients with Single Right Ventricles

Increased ventricular end-diastolic pressure (VEDP) is a known risk factor for morbidity and mortality in patients with single-ventricle physiology. Spectral Doppler tissue imaging (DTI) has been shown to modestly correlate with direct measurement of VEDP. Strain rate (SR) values, obtained via myocardial deformation, have not yet been compared with VEDP in this patient population. The goal of this study was to evaluate which of these imaging...
