Uncovering right ventricular impairment in severe TR: Insights from novel volumetric indices.
BACKGROUND Accurate assessment of right ventricular (RV) performance is crucial in patients with severe tricuspid regurgitation (TR). Conventional RV ejection fraction (RVEF) may overestimate RV systolic function because it does not account for regurgitant volume in severe TR. This study aimed to evaluate the prognosti...
