Previous studies have demonstrated that the radionuclide right ventricular (RV) ejection fraction (RVEF), tricuspid annular plane systolic excursion (TAPSE), and tissue Doppler peak systolic tricuspid annular velocity (STr) were independent predictors of cardiac survival in stable patients with left ventricular systolic dysfunction (LVSD). No study has compared the prognostic value of these three RV parameters. The aim of this study was to compare the prognostic value of RVEF, TAPSE, and STr in a large group of patients with LVSD.
