Coexistence of Patent Ductus Arteriosus and Congenital Aortic Valvular Disease

Abstract

Congenital aortic or subaortic stenosis was demonstrated in 7 of 50 patients with patent ductus arteriosus. In addition to the murmurs characteristic of each lesion and diagnostic carotid artery pulse tracings, inordinate enlargement of the left ventricle with a small shunt through the patent ductus should suggest involvement of the aortic valve. The clinical findings associated with this combination of lesions are clear cut and awareness of them should lead to more frequent identification than has been reported previously.
