Giant anastomotic pseudoaneurysm after Bentall operation causing late postoperative cardiogenic shock.

Pseudoaneurysm of the ascending aorta is a rare but severe complication occurring after composite graft surgery for combined aortic valve and ascending aorta disease. The diagnosis of this condition can be difficult because anastomotic pseudoaneurysms show highly variable clinical features depending on the site of the aortic dehiscence and on the involvement of the surrounding structures. We report an unusual case of a late postoperative aortic graft dehiscence, causing acute right heart failure.
