Abstract:Purpose:We recently reported a noninvasive method for the assessment of right ventricular (RV) operating stiffness that is obtained by dividing the atrial-systolic descent of the pulmonary artery-RV pressure gradient (PRPGDAC) derived from the pulmonary regurgitant velocity by the tricuspid annular plane movement during atrial contraction (TAPMAC). Here, we investigated whether this parameter of RV operating stiffness, PRPGDAC/TAPMAC, is useful for predicting the prognosis of patients with heart failure (HF… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
