Vascular Malformation Overlying the Pulmonary Artery Simulating a Patent Ductus Arteriosus

CALVIN B. ERNST M.D.¹; KARL P. KLASSEN M.D.¹; JOSEPH M. RYAN M.D.¹

¹ From the Division of Cardiology and Thoracic Surgery, Ohio State University Health Center, Columbus, Ohio.

An arteriovenous fistula with aneurysmal dilatation involving branches of both coronary vessels and the pulmonary artery is discussed.

The malformation was limited to the main pulmonary artery and presented a small left-to-right shunt without symptoms.

Ligation of the supplying vessels resulted in the disappearance of a murmur typical of a patent ductus arteriosus.
