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

ConclusionRV –PA coupling predicts one-year mortality and heart failure rehospitalization after TTVR in patients with TR. The predictability is improved if invasively-measured PA pressure is included.Graphical abstractAssessing right ventricular (RV) function is paramount for risk stratification. The present analysis confirms that RV –PA coupling, measured as TAPSE/PASP, predicts one-year mortality and heart failure rehospitalization in patients undergoing TTVR. There is a significant interaction between TR severity and the correlation of ePASP with iPASP, and therefore the correlation is attenuated in patients with massive to torrential TR. The predictability of RV–PA coupling is improved if PA pressure is measured invasively and included in the formula.
