Abstract
The authors present their experience of percutaneous aortic valvuloplasty in 10 neonates and 12 children with critical aortic stenosis. In the neonate group the left ventricular aortic gradient dropped from 49 +/- 20 mmHg to 15 +/- 16 mmHg. This improvement persisted in 57 p. cent of the cases after 2 years. In the older group (mean age 6 years) the gradient was reduced from 73 +/- 22 mmHg to 30 +/- 17 mmHg with maintained results in 78 p. cent after 2 years. Aortic incompetence occurred in the majority of cases but did not seem to be more important than after surgical commissurotomy. In critical stenosis, balloon aortic valvuloplasty seems to be a valuable alternative to surgery as a palliative measure before prosthetic valve replacement.
