Medical therapy alone is insufficient, and either TEER (transcatheter edge-to-edge) or surgery is recommended. Short-and long-term comparative outcomes remain unclear. We aim to address this gap using available data.  \nAuthor Contributions: S. Khairallah and M. Rahouma contributed equally to this work.  \n© The Author(s) 2025.

MEDLINE, EMBASE, and the Cochrane Library were assessed. The incidence rate of late severe MR was the primary outcome. A random model was performed. Leave-one-out, subgroup, and meta-regression analyses were conducted.  \nRESULTS: Thirty-two studies (1923 patients); 20 in surgery (1166) vs 12 in TEER (757), were selected. TEER patients were, on average, 10 years older, with twice the rate of New York Heart Association Classification (NYHA) III/IV symptoms and more than double the Society of Thoracic Surgeons Risk (STS) score. At a weighted mean follow-up of 3.2 years, compared to isolated transcatheter, surgery was associated with decreased incidence of late severe MR (2.53 vs 6.66 events per 100 person-years, P-interaction ¼ .03), late all-cause mortality (3.00 vs 8.84, P-interaction ¼ .024), late heart failure hospitalization (4.44 vs 17.03, P-interaction \u003C .01), and late NYHA III/IV (2.98 vs 22.47, P-interaction \u003C .01). However, significantly better long-term outcomes associated with surgery showed high heterogeneity. There were no differences in early all-cause mortality, early cardiac-specific mortality, late cardiac-specific mortality, postprocedural morbidities, or atrial diameter.
