Early outcome of mitral valve repair in rheumatic mitral regurgitation.

Abstract

Objectives: To evaluate and record the early outcomes of mitral valve repair in patients with rheumatic mitral valve regurgitation in advanced functional classes (NYHA III/IV). Study Design: Prospective Observational study. Setting: Department of Cardiac Surgery, Faisalabad Institute of Cardiology, Faisalabad. Period: March, 2023 to March, 2025. Methods: One hundred and thirty patients having rheumatic mitral valve regurgitation in functional class (NYHA) III/IV were studied. Baseline demographical informations, perioperative, and initial postoperative outcomes were documented. Early (less than 30 days) mortality was taken as primary outcome measures, and secondary outcome measures were postoperative complications, ICU and hospital stay, and early echocardiographic valve function. Results: A successful repair was done on the patients having rheumatic mitral valve regurgitation having satisfactory post-operative morbidity and mortality rates. Majority of the patients exhibited satisfactory initial valve competency and none or mild residual mitral regurgitation on pre-discharge echocardiography. The initial results were similar to those of modern repair-based cohort and pool reports, indicating the safety of repair in the selected rheumatic patients. Conclusion: In rheumatic mitral regurgitation, mitral valve repair is linked to good short-term results in case of an appropriate patient selection.
