A pediatric perspective on the TAPSE/PASP ratio in pulmonary arterial hypertension

With interest we read the article by Tello et al. [1] on the tricuspid annular plane systolic (TAPSE)/pulmonary artery systolic pressure (PASP) ratio used for echocardiographic estimation of pulmonary vascular resistance (PVR), pulmonary arterial capacitance, and functional capacity (WHO-FC) in adults with pulmonary arterial hypertension (PAH) [1]. We further agree with Guazzi's editorial and previous work suggesting that the TAPSE/PASP ratio represents an indicator of right ventricular (RV) to pulmonary circulation (PC) coupling [2,3].
