Prognostic Implications of Right Ventricular Remodeling and Function in Patients With Significant Secondary Tricuspid Regurgitation

BACKGROUND:In patients with significant (moderate and severe) tricuspid regurgitation (TR), the decision to intervene is influenced by right ventricular (RV) size and function. RV remodeling in significant secondary TR has been underexplored. The aim of this study was to characterize RV remodeling i...

Description
Summary:BACKGROUND:In patients with significant (moderate and severe) tricuspid regurgitation (TR), the decision to intervene is influenced by right ventricular (RV) size and function. RV remodeling in significant secondary TR has been underexplored. The aim of this study was to characterize RV remodeling in patients with significant secondary TR and to investigate its prognostic implications. METHODS:RV remodeling was characterized by transthoracic echocardiography in 1292 patients with significant secondary TR (median age 71 [62–78]; 50% male). Four patterns of RV remodeling were defined according to the presence of RV dilation (tricuspid annulus≥40 mm) and RV systolic dysfunction (tricuspid annulus systolic excursion plane
