[A case of surgical treatment of patent ductus arteriosus using left heart bypass in an adult].

This paper describes a new operative method for patent ductus arteriosus using left heart bypass. A 57-year-old woman with patent ductus arteriosus associated with severe pulmonary hypertension was successfully operated upon. Because of aneurysmal dilatation and calcification of the aortic side of the ductus, PDA was divided under left heart bypass with centrifugal pump. Postoperative course was uneventful, and is now well.
