title: Early results after mitral valvuloplasty for pure mitral regurgitation.
abstract: In this study we present the results of 105 consecutive patients with pure mitral regurgitation who underwent surgical treatment. In all patients mitral regurgitation was associated with mitral valve prolapse: 54 patients underwent mitral valvuloplasty and 51 patients mitral valve replacement. Clinical assessment and echocardiography were used as follow-up criteria at one year after surgery. After mitral valvuloplasty, NYHA decreased from 2.7 +/- 0.8 to 1.1 +/- 0.7 (P less than 0.01) and workload capacity increased from 65 +/- 28% to 96 +/- 25% (P less than 0.001); left endsystolic atrial dimension and enddiastolic dimension decreased from 6.2 +/- 0.8 to 4.8 +/- 1.2 cm (P less than 0.001) and from 7.2 +/- 1.3 to 5.9 +/- 0.8 cm (P less than 0.01); ventricular contraction fraction did not change significantly. After mitral valve replacement, clinical and echocardiographic improvement was significant but less remarkable than after valvuloplasty; ventricular contraction fraction fell from 39 +/- 7% to 29 +/- 8% in contrast to patients undergoing mitral valvuloplasty in whom no significant change occurred. Complications were rare in both groups though only a minority of patients undergoing mitral valvuloplasty received anticoagulants. We conclude that mitral valvuloplasty in patients with pure mitral regurgitation when compared with the patients after mitral valve replacement.
