Abstract
Introduction:
Balloon angioplasty has been successfully used to dilate vascular obstructions. However, its value in some conditions such as supravalvular pulmonary stenosis is still controversial. Although some surgical techniques have been reported to achieve acceptable short- and long-term successes, they are invasive and technically challenging and may result in higher morbidity and mortality compared to percutaneous procedures.
Case Presentation:
Successful balloon dilatation was reported for two patients with supravalvular stenosis. One of them had supravalvular pulmonary stenosis developed after pulmonary artery debanding and the second one had supravalvular pulmonary stenosis due to an obstructive congenital web at that site.
Conclusions:
The use of balloon dilatation to treat supravalvular pulmonary stenosis is still controversial. However, experiences in two patients showed successful results.
