Assessment of Right Ventricular Function Prior to Transcatheter Tricuspid Valve Interventions.

PURPOSE OF REVIEW: Right ventricular (RV) function is a key determinant in selecting and managing patients undergoing transcatheter tricuspid valve replacement (TTVR) or transcatheter tricuspid edge-to-edge repair (T-TEER). This review aims to highlight the role of multimodality imaging in assessing RV function, with a focus on its impact on patient selection, procedural planning, and prognostic evaluation. RECENT FINDINGS: Advances in echocardiography, cardiac magnetic resonance imaging, cardiac computed tomography, and right heart catheterization have improved the ability to evaluate RV morphology, systolic performance, and pulmonary hemodynamics. Each modality offers complementary insights, though limitations remain in standardization, reproducibility, and prognostic validation. Emerging imaging strategies and novel functional parameters provide opportunities for more refined risk stratification. Integrating multimodality imaging enables a comprehensive evaluation of RV function and enhances decision-making prior to TTVR and T-TEER. A tailored imaging approach improves patient selection and may ultimately optimize outcomes in severe tricuspid regurgitation.
