Mitral valve repair with aortic valve replacement in rheumatic heart disease.
From 1992 to 2001, 609 patients with rheumatic heart disease underwent aortic valve replacement with either mitral valve repair (n = 201) or mitral valve replacement (n = 408). Follow-up extended to 10 years. Thirty-day mortality was 1.4% for mitral valve repair and 0.7% for mitral valve replacement (p = 0.4). Survival at 9 years was 96.5 +/- 1.4% after mitral valve repair and 89.7 +/- 7.8% after mitral valve replacement (p = 0.73). Freedom from major bleeding at 9 years was 94.8 +/- 2.4% after mitral valve repair and 81 +/- 7.2% after mitral valve replacement (p = 0.03). Freedom from other valve-related complications and from mitral valve re-operation was similar for the two groups. This study showed that in patients with rheumatic heart disease the results of mitral valve repair with aortic valve replacement were comparable to those of double valve replacement. Major bleeding was less frequent after mitral valve repair with aortic valve replacement. Therefore, whenever feasible, mitral valve repair should be attempted in patients with rheumatic heart disease who need concomitant aortic valve replacement.
