[Immediate and mid-term results of balloon valvuloplasty in congenital aortic stenosis. Ten case reports].
From 1987 to 2000, 10 patients aged 0.5 to 20 years with congenital valvular aortic stenosis underwent percutaneous balloon aortic valvuloplasty. In one patient, balloon valvuloplasty was unsuccessful, this patient had acute artery thrombosis requiring surgical intervention. Hemodynamically successful dilatation was achieved in 9 patients. The peak systolic pressure gradient was reduced from 76 +/- 35 to 32 +/- 16 mmHg (p < 0.001). Aortic valve regurgitation on angiography appeared or increased in 2 patients (up to grade 2 in the 2 patients). There was no deaths during the procedure. Follow-up was available in 7 patients One patient died during the follow up period. Restenose was found in only one patient 5 years after valvuloplasty and the efficacy balloon aortic valvuloplasty continued significantly in 5 patients (mean follow-up 35 +/- 18 months) with a residual aortic valvular gradient of 34 +/- 15 mmHg.
