Percutaneous balloon aortic valvulotomy in childhood

We assessed the effectiveness of balloon valvuloplasty in 34 children who were admitted for aortic valve balloon dilatation over 7 years (97-03) in two institutions (Stuttgart, Zagreb) with prevalence of male (28/6), age dilatation 35.61+/-55.39 months, BW 13.1 +/- 15.9 kg.Fifteen of them (47%) had no clinical symptoms, 12 (35.3%) were dyspnoic, and 6 (17.6%) in sever heart failure. According to ECHO, ventricular function was normal in 6 (17.6%), moderately limited in 17 (50%)and severely impaired in 11(32.4%) pts. Immediately aftzer valvuloplasty the mean systolic pressure gradient across the aortic valve decreased from 70.62+/-20.78 to 20.03+/-13.7. The balloon/aortic valve ring ratio was 0.85+/-0.09. long term results were studied in 30 patients 1-72 months after valvuloplasty and revealed continuously increasing residual aortic valve gradient 31.35+/-12.01, atill being significantly lower than before valvuloplasty. On following aortic regurgitation increased to grade 3 in 3(10%) and to grade 2 in7 (23.3%) pts. Eight required reintervention, one of them balloon valvuloplasty only, 4 baloon valvuloplasty and surgery and 3 surgery only. The overall actual survival after 7 years was 96.6%. The freedomof any reintervention was 76%, 73% and 61%, and for surgical reintervention 88%, 85% and 79% at 2, 4 and 7 years
