Clinical value of a novel three-dimensional echocardiography derived index of right ventricle-pulmonary artery coupling in tricuspid regurgitation

Echocardiographic surrogates of right ventricle (RV) to pulmonary artery (PA) coupling have been reported to be associated with outcomes in secondary tricuspid regurgitation (STR). However, pulmonary artery systolic pressure (PASP) is difficult to estimate using echocardiography in patients with severe STR. The aim of the present study was to evaluate the predictive power of a surrogate of RV/PA coupling obtained using RV volumes measured by three-dimensional echocardiography (3DE).
