DIAGNOSIS AND OUTCOMES OF PATIENTS WITH SUPRAVALVULAR PULMONARY STENOSIS TREATED WITH PERCUTANEOUS BALLOON DILATION

Congenital supravalvular pulmonary stenosis (PS) is a rare subtype of PS. Outcomes following percutaneous dilation of the pulmonary artery (PA) and pulmonary valve (PV) seem to be dependent on the presence of a supravalvular component. The aim of this study was to determine the reliability of echocardiography in identifying the origin of the PS and to evaluate the efficacy of percutaneous dilation of supravalvular stenosis. Retrospective study...
