Hosts Mitsuaki Sawano, MD, Nobu Ikemura, MD, and Satoshi Shoji, MD welcome Dr. Shingo Matsumoto, MD (Toho University) and Dr. Yohei Ohno, MD (Tokai University) to discuss their JACC: Cardiovascular Interventions study, "Atrial Fibrillation and Tricuspid Regurgitation in Patients Undergoing Mitral Valve Transcatheter Edge-to-Edge Repair." Building on prior evidence that residual tricuspid regurgitation (TR) influences outcomes after M-TEER, this analysis examines how atrial fibrillation (AF) interacts with TR progression and right ventricular remodeling. In a large OCEAN-Mitral cohort, AF was associated with greater TR persistence and progression after M-TEER, distinct patterns of right ventricular dysfunction, and amplified risk of cardiovascular death or heart failure hospitalization when moderate-or-greater TR remained post-procedure. The discussion reframes post–M-TEER management beyond the mitral valve alone, highlighting the importance of right-heart assessment, TR surveillance, and the evolving role of AF in shaping structural heart outcomes.
