Rj. Pinto et al., BALLOON DILATATION OF SUPRAVALVULAR AORTIC-STENOSIS - A REPORT OF 2 CASES, International journal of cardiology, 46(2), 1994, pp. 179-181
Balloon dilatation was performed in two cases of supravalvular aortic
stenosis with variable results. There was remarkable reduction in grad
ient in the patient with membranous obstruction and the benefits are s
ustained at 18 months follow-up. The patient with hour-glass obstructi
on had only a partial success with reappearance of obstruction within
1 week. Balloon dilatation may emerge as a viable treatment modality f
or membranous obstructions. However, a large study is needed to establ
ish the place of this procedure.
