ABSTRACT
Objective: To analyze the outcome of mitral valve repair in rheumatic heart disease
Study Design: Retrospective analytical
Place and Duration of Study: Armed forces institute of cardiology/National institute of heart diseases Rawalpindi from Jan 2011 to June 2013
Material and Methods: In this retrospective study of 28 patients [15 females]. The mean age was 20.2 +/- 11.2 years [range, 11 to 55 years]. The cause of mitral regurgitation was rheumatic in all patients, with no congenital myxomatous, infective or ischemic cases. About 68% patients were in New York Heart Association [NYHA] functional class III or IV. In all the cases posterior ring annuloplasty was done with flexible C- Shape rings with size ranging from 20 to 26 mm. Repairs included anterior leaflet repair with cusp shortening and resuspension [n=17], posterior leaflet repair with quardranguloplasty and transpositioning [n=6], commissuroplasty [n=2] and mixed anterior posterior leaflet repair [n=3]
Results: There was no operative mortality. Follow-up was carried out for 10 months. The trivial mitral regurgitation was found in 3 cases [10.7%]. Four [14.2 %] patients required mitral valve replacement due to valve dysfunction
Conclusion: Mitral valve repair in rheumatic patients, with current techniques, can effectively correct functional and hemodynamic abnormalities with satisfactory results
