Results of mitral valve repair in rheumatic valvular heart disease

Aim: This retrospective study was planned to evaluate the various outcomes of mitral valve repair in rheumatic mitral valve disease. Methods: Between January 2007 to July 2015, 238 rheumatic mitral valve repair was done at our institution. The data was collected retrospectively and various post-operative outcomes were analysed in term of mortality, rate of survival, re-operation rate, NYHA class and thromboembolism & bleeding complications. Mitral valve was assessed by transthoracic echocardiography and various results were analysed. Results: Mean age of study population was 32.17±11.90. 56.72% were female patients. Early mortality was 5.62% and late mortality was 3.13%. Mean follow up was 71±23 months. Survival at mean follow up was 91.59%. Freedom from re-operation was 95%. The rate of re-do procedure was 4.12%. Residual pathology was present in 6.25%. The post-operative mean NYHA class, mitral valve area, mean gradient across mitral valve were 1.34±0.741, 3.17±0.58, 3.81±0.92 respectively. Conclusion: Mitral valve repair in Rheumatic heart disease is possible in majority of patients with excellent results when comprehensive repair techniques are used.
