Right Ventricular–Pulmonary Arterial Coupling by Serial TAPSE/sPAP: A Noninvasive Predictor for Clinical Outcomes in Chronic Thromboembolic Pulmonary Hypertension
ABSTRACT The ratio of tricuspid annular plane systolic excursion to systolic pulmonary artery pressure (TAPSE/sPAP) is a noninvasive surrogate of right ventricular–pulmonary arterial coupling, but its value for dynamic risk stratification in chronic thromboembolic pulmonary hypertension (CTEPH) remains uncertain. This...
