title: [Congenital percutaneous aortic valvuloplasty in 70 subjects with congenital aortic stenosis, mid-term results].
abstract: OBJECTIVE
  To evaluate mid-term results with Percutaneous aortic valvuloplasty (PAV).
  
  
  METHODS
  Records of 70 patients treated with percutaneous aortic valvuloplasty with at least 6 months follow-up were reviewed.
  
  
  RESULTS
  The 70 patients with PAV aged 3 months to 36 years, mean 10.5 +/- 10.6 years, 40) 63%) were male and 26 (37%) female. Initial systolic peak gradient decreased from 84 +/-20 to 31 +/- 16 mmHg (p < 0.05), while the reduction percentage ranged from 25 to 100%, mean 60 +/- 22. Balloon/aortic annulus index was 0.9 +/- 0.17. Ten (14.1 %) patients developed aortic insufficiency after PAV. Follow-up ranged from 6 to 168 months, mean +/- 48 months. At end of follow-up, 21 patients (30%) were considered failed cases and 49 (70%) patients had a successful outcome.
  
  
  CONCLUSIONS
  This study showed a series with the longest follow-up in Latin America with PAV. New prospective and multicentric studies are needed in this region.
