      Abstract :

      Objective. To assess the outcome after attempted percutaneous balloon dilatation of the mitral valve in patients with mitral stenosis between August 1993 and November 1994. Design and methods. 40 patients had echocardiography evaluation before and immediately after Percutaneous transvenous Mitral Commissurotomy (PTMC) and at mean follow-up time of 36  5.22 months after PTMC. Result. There were 12 men (30 %) aged 37.08  14.29 years and 28 women (70%) aged 36.71  9.78 years. Systolic pulmonary artery pressure was 64.88  14.07 mmHg, before PTMC decreased to 46.47  7.93 mmHg ( p = 0.000 ) and 41.08  8.34 mmHg ( p = 0.000 ) at follow-up ( p = 0.000 ). Left atrial diameter was 46.77  5.81 mm before PTMC decreased to 43.27  5.63 mm ( p = 0.000 ) and became 39.95  6.49 mm at follow-up ( p = 0.000 ). Planimetri of the mitral valve area was 0.96  0.22 cm2 before PTMC, increased to 1.74  0.17 cm2 immediately after ( p = 0.000 ) and then decreased to 1.64  0.18 cm2 ( p = 0.000 ). Doppler measurements was 0.96  0.22 cm2 before PTMC increased to 1.78  0.25 cm2 ( p = 0.000 ) immediately after PTMC and then decreased to 1.67  0.17 cm2 (p = 0.000 ) at follow-up. Restenosis had developed in 1 patients (2.5%) The degree of mitral regurgitation increased from grade 0 to 1+ in 7 patients after PTMC and was unchanged at follow-up. No patient developed severe mitral valve regurgitation. Conclusion. This study demonstrates that the excellent early results of a successfully PTMC are maintained over a 36  5.22 months as reflected by a low anatomic restenosis rate (2.5 %) and sustained clinical benefits.
