Percutaneous mitral valvuloplasty (PMV) was performed with Inoue's catheter, by anterograde approach, in 19 patients (2 males and 17 females, mean age of 56 +/- 13 years) with restenosis after surgical commissurotomy. Mean valvular area increased from 1.2 +/- 0.2 to 1.9 +/- 0.2 cm2 while mean transvalvular gradient decreased from 13 +/- 6 to 7 +/- 4 mmHg. All but 2 patients reached optimal results; one had a suboptimal result (final valvular area > 1.5 cm2, percentage of increase less than 25%), and 1 was sent to the surgeon for a significant increase in mitral regurgitation ( ). At 1 year follow-up, (available for 11 patients), mean valvular area was 1.7 +/- 0.3 cm2 and transmitral gradient was of 5.4 +/- 2 mmHg. Four patients showed a restenosis; 1 of them underwent surgical mitral valve replacement after a second unsuccessful PMV; 2 showed good clinical conditions, while the fourth patient was sent to the surgeon for the high echocardiographic score. At 2-year follow-up, available for 4 patients, the mean gradient was of 5.5 +/- 2.5 mmHg and the mitral valve area was 1.8 +/- 0.2 cm2. NYHA functional class progressively improved after the procedure in all patients but those undergoing mitral valve replacement. In conclusion, despite the occurrence of restenosis, PMV seems to be feasible in patients who already underwent surgical commissurotomy; this procedure can avoid the risks of a second surgery, and should be considered the first choice treatment in these patients.
