Refining accuracy of RV-PA coupling in patients undergoing transcatheter tricuspid valve treatment.

ABSTRACT:

Background

Assessing right ventricular (RV) function is paramount for risk stratification, which remains challenging in patients with tricuspid regurgitation (TR). We assessed RV-pulmonary artery (PA) coupling and its predictability of outcomes after transcatheter tricuspid valve repair (TTVR).

Methods

Study participants comprised patients undergoing transcatheter tricuspid valve repair to treat symptomatic TR from June 2015 to July 2021. We calculated an RV-PA coupling ratio using a formula, which is dividing tricuspid annular plane systolic excursion (TAPSE) by echocardiographically estimated (ePASP) or invasively measured PASP (iPASP) at baseline. The primary outcome was all-cause mortality or heart failure rehospitalization within one year.
