- Abstract
Objective: To evaluate the outcomes of transcatheter edge-to-edge repair (TEER) with MitraClip™ (Abbott Vascular) in symptomatic high surgical risk Indian patients with significant mitral regurgitation (MR)., Methods: Patients with moderately severe or severe primary or secondary MR and deemed high surgical risk were treated with MitraClip™. The data were collected retrospectively from medical records. The primary outcome was technical success, and secondary outcomes were ≤2+ MR reduction and improvement in functional capacity at 30 days., Results: Between November 2018 and August 2023, 64 patients were treated with MitraClip
TM . The mean age was 70.0 ± 12.1 years and 64 % were males. The mean EuroScore II and STS score predicted mortality for mitral valve repair were 5.8 ± 4.5 % and 4.0 ± 3.8 % respectively. MR etiology was primary in 56.3 %, secondary in 40.6 % and mixed in 3.1 %. The device was implanted successfully in all but one patient with technical success rate of 98.4 %. The average number of clips per patient was 1.5 ± 0.6 and 42.2 % patients received more than one clip. The mean mitral valve gradient was 3.5 ± 1.6 mmHg. The MR severity of ≤2+ was achieved in 91.8 % of the subjects and similar proportion were in New York Heart Association Functional Class I or II at 30 days., Conclusion: In high-risk Indian patients with symptomatic significant MR, TEER with MitraClip™ was achieved with a high technical success rate. It was associated with significant reduction in MR severity and improvement in functional capacity in >90 % of the subjects., Competing Interests: Declaration of competing interest COI disclosure enclosed., (Copyright © 2024 Cardiological Society of India.
