title: [Efficacy and experience in right ventricular pacing-percutaneous balloon aortic valvuloplasty].
abstract: OBJECTIVE
  To evaluate the efficacy and experience in right ventricular pacing-percutaneous balloon aortic valvuloplasty (RVP-PBAV) for congenital aortic stenosis (AS).
  
  
  METHODS
  A total of sixteen children with AS accepted the treatment with RRVP-PBAV. The patients were at ages 6 months to 15 years, their median age was 5.4 years. Their body weight was between 8.5 and 59.0 kg, average (22.3 ± 16.5) kg. The gradient pressure across the aortic valve was measured for all the patients and aortic regurgitation was observed. The follow-up time ranged from 1 month to 5.5 years.
  
  
  RESULTS
  All patients underwent RVP-PBAV successfully. The ratios of balloon/valve were 0.86 to 1.12. The gradient pressure varied from preoperative Δp = (96 ± 32) mmHg (1 mmHg = 0.133 kPa) to the immediate postoperative ΔP = (41 ± 26) mmHg, (P < 0.05). One case had postoperative restenosis, and 3 cases were complicated with bicuspid aortic valve deformity.
  
  
  CONCLUSIONS
  The treatment with RVP-PBAV for congenital aortic stenosis is safe and reliable. Rapid ventricular pacing is a safe procedure to stabilize the balloon during balloon aortic valvuloplasty and may decrease the incidence of aortic insufficiency.
