Mitral valve repair for pure mitral regurgitation and mixed mitral valve disease

ABSTRACT

Out of all mitral valve salvage cases done at the Punjab Institute of Cardiology, Lahore between 1991 and April 1994, 60 cases operated upon by one surgeon were selected for study. There were 4 [6.67%] hospital and 2 late deaths. Three patients including one late death underwent mitral valve replacement at a later stage. Six patients were lost to follow up. The remaining 46 patients are being followed up to assess the success of the repair or otherwise in terms of the New York Heart Association [NYHA] functional class of the patients and echocardiographic findings. All our patients dad rheumatic involvement of the mitral valve. The associated cardiac lesions were ASD in 2 [3.33%], tricuspid regurgitation in 40 [66.67%] and aortic regurgitation in 23 [38.33%] patients. The age range was between 10 and 50 years. The follow up period was 3-43 months. Forty [86.96%] patients are in functional class I or II while 6 [13.04%] patients are in functional class III or IV. Twenty-five [54.35%] patients have trivial or mild mitral regurgitation on post operative echocardiogram while 14 [30.43%] have moderate mitral regurgitation. We conclude that satisfactory results can be obtained with repair even in cases with rheumatic mitral valve disease
