Abstract

Objectives: To evaluate the results of mitral valve repair in patients with mitral regurgitation. Methods:A retrospective, descriptive study without a control group was conducted on 52 patients with chronic mitral regurgitation who underwent mitral valve repair at Military Hospital 103, from June 2018 to August 2024. Results:The mean age was 59.9 ± 11.6, ranging from 31 to 79, and the male-to-female ratio was 2.7/1. A total of 73.1% of patients were classified as NYHA II, and 26.9% had NYHA III. 30.8% of patients had atrial fibrillation; 69.2% had sinus rhythm. Intraoperative findings were noted in posterior valve leaflets (38.5%), anterior valve leaflets (34.6%), and both valve leaflets (23.1%), while 3.8% of individuals had simple valve annular dilatation. Mitral valve repair was successfully performed in 98.1% of cases, while 1.9% failed. Neo-chordae were implanted in 45.1% of patients, and 49/51 patients underwent mitral valve annuloplasty with a ring.Tricuspid valve repair was performed in 58.8% of patients, and coronary artery bypass grafting in 9.8% of patients. The average cardiopulmonary bypass time was 145.7 ± 38.9 minutes, and the aortic cross-clamp time was 107.5 ± 30.1 minutes. Postoperative complications were observed in 4 cases with low cardiac output syndrome, requiring intra-aortic balloon pump implantation, and 2 patients having wound infections. No deaths were recorded during the follow-up period. At the end of the study, 84.3% of patients were classified as NYHA I, and only 2 patients had moderate mitral regurgitation. Conclusion: Mitral valve repair for mitral regurgitation provides excellent surgical outcomes, with high survival rates and a low rate of complications.
