Incidental discovery of a large patent ductus arteriosus in an adult during aortic reconstruction: echocardiographic findings and diagnostic dilemmas.

摘要

A61-yr-old woman presented with sudden back pain. She had had a Stanford type A aortic dissection 15 yr earlier repaired with a Bentall procedure with a St. Jude aortic valve replacement. Her prior reconstruction extended from the aortic root to the brachio-cephalic artery. An intraoperative echocardiogram was not performed at the time. She subsequently developed a chronic Stanford type B dissection at the distal aortic arch.
