Abstract

Balloon dilatation of congenital stenotic lesion of the pulmonic valve has been used. Repeated balloon dilatation of restenosed lesion after previous balloon dilatation for the pulmonic stenosis is needed in some case. We treated a case of pulmonic restenosis with using three balloon catheters in a boy. The most critical problems related the valvuloplasty are severe systemic hypotension and bradycardia due to stasis of blood flow. The use of three balloon catheters instead of single or double balloons for the pulmonic stenosis could be a alternative interventional method to preserve the preexistent forward blood flow during inflation and to minimize vascular injury in children with large valve annulus.
