Abstract

Objectives: In this study, we present the mid-term results of patients who underwent valve repair due to degenerative mitral valve regurgitation in the first five years of our mitral valve repair program.

Patients and Methods: In this retrospective study, all patients who were operated for degenerative mitral regurgitation by a single surgical team between 2013 and 2017 were investigated. We determined early and mid-term cumulative survival rates, repair failure and freedom from reoperation. In addition, as a specific subgroup, the results of patients under 18 years of age after mitral valve repair were investigated

Results: Mitral repair was performed in 121 of 153 degenerative mitral regurgitation patients during the study period. The overall repair rate was 79%. Mitral valve repair rate increased significantly over years. The Median follow-up time was 63 (range 10-92) months. Early mortality was 2.5% (n=3 patients). During the follow-up period, moderate-to-severe mitral regurgitation was observed in 14 (11.8%) patients, mitral valve reoperation was required in 7 (5.9%) patients. Valve repair was performed in 4 of 7 patients under the age of 18. There was no pediatric case requiring reoperation during the follow-up period (median 46 months).

Conclusion: Mid-term results of mitral valve repair in degenerative mitral valve patients are satisfactory. The success rate of repair increases in line with surgical experience.
