title: [Balloon valvuloplasty outcome of a group previously submitted to mitral percutaneous or surgical valve repair versus first-time valvuloplasty patients. Evolution of the group previously submitted to valve repair procedures].
abstract: OBJECTIVE
  To evaluate 501 procedures of mitral balloon valvuloplasty and the differences among the group already submitted the prior surgical or balloon valvuloplasty, with 59 procedures and the group without previous intervention, with 442 procedures.
  
  
  METHODS
  It was used the single balloon in 403, Inoue balloon in 89 and a double balloon in six, with no difference between the 2 groups (p=0.6610).
  
  
  RESULTS
  The prior surgical or balloon valvuloplasty group was older, with higher echo score and higher atrial fibrillation rate and of its 59 patients, 48 had been submitted only to mitral surgical commissurotomy, 8 only to mitral balloon valvuloplasty and 3 to surgical commissurotomy and after submitted to balloon valvuloplasty because of restenosis. In prior surgical or balloon valvuloplasty and mitral balloon valvuloplasty without previous intervention groups pre valvuloplasty there were respectively: echo mitral valve area 0.99+/-0.21 and 0.94+/-0.21 cm2 (p=0.0802) and mitral valve area (Gorlin) 0.94+/-0.18 and 0.91+/-0.21 cm2 (p=0.2518) and post mitral valvuloplasty 1.95+/-0.44 and 2.05+/-0.42 cm2 (p=0.1059).
  
  
  CONCLUSIONS
  The hemodynamic and angiographic outcome of the prior surgical or balloon valvuloplasty group were similar to the group without previous intervention. The evolution was satisfactory in the prior valvuloplasty subgroup with long-term follow-up.
