Concomitant Transcatheter Edge-to-Edge Treatment of Secondary Tricuspid and Mitral Regurgitation: An Expert Opinion.

Abstract

Secondary (functional) tricuspid regurgitation (sTR) is common in patients with mitral regurgitation (MR). Because combined valvular heart disease affects long-term survival, in comparison with isolated MR or tricuspid regurgitation, it is essential to offer patients adequate treatment. Despite considerable experience, no conclusive data are yet available on the prognostic impact of concomitant tricuspid valve surgery at the time of mitral valve surgery. Emerging transcatheter treatments offer the opportunity to treat both conditions (MR and sTR) simultaneously or in a stepwise fashion. This review provides a clinical overview on available data regarding the rationale for treatment of sTR in patients with relevant MR undergoing mitral transcatheter edge-to-edge repair, focusing on clinical and anatomical selection criteria.
