Echocardiography-derived effective pulmonary arterial elastance predicts mortality after transcatheter aortic valve replacement
Right ventricular–pulmonary arterial (RV–PA) uncoupling influences outcomes after transcatheter aortic valve replacement (TAVR). Effective pulmonary arterial elastance (EPA), calculated non-invasively as right ventricular systolic pressure divided by stroke volume (RVSP/SV), integrates pressure and flow to quanti...
