Abstract

Background: Management of mitral regurgitation recurrence after failed surgical valve repair with ring implantation is controversial. Aim: To describe the French experience regarding midterm safety and efficacy of transcatheter edge-to-edge mitral valve repair (TEER) in patients with failed surgical valve repair with ring implantation. Methods: The “Clip-in-Ring” registry is a multicentre registry conducted in 11 centres in France, approved by local institutional review boards, of consecutive TEER following surgical valve repair with ring implantation. Outcomes were Mitral Valve Academic Research Consortium (MVARC) technical success, modified 30-day device and procedural success (where 10 mmHg is considered as a cut-off for significant mitral stenosis) and MVARC complications. Results: Twenty-three patients were studied: mean age, 69 ± 10 years; male sex, 74%; EuroSCORE II, 16 ± 17; left ventricular ejection fraction, 53 ± 12%; mitral regurgitation grade 3+/4+, 17%/78%; New York Heart Association class III/IV, 47%/22%; median surgery to TEER delay, 23 (6–94) months. Technical success was 100%. At discharge, residual mitral regurgitation grade was ≤ 2+ in 87% and median transmitral gradient was 4 (3–5) mmHg. Thirty-day modified MVARC device and procedural success was 82%: four patients (17%) had residual mitral regurgitation grade > 2+, including two patients who needed complementary surgery. No patient had a 30-day transmitral gradient > 7 mmHg. No patient died or had a stroke or any life-threatening complications. One patient presented a vascular access complication requiring transfusion. No other MVARC-2 adverse event was reported. Conclusions: TEER in patients with failed mitral ring is feasible and safe. Further studies should delineate its exact role in the therapeutic armamentarium for this medical issue.
