Ascending aortic dissection after proximal bypass anastomotic device.

ABSTRACT

Ascending aortic dissection is a known complication of cardiac surgery. Different type of devices allowing performance of proximal bypass anastomoses without aortic side-clamping are supposed to reduce the risk for aortic dissection. We report a case in which ascending aortic dissection occurred six months after off-pump coronary artery bypass surgery, with the entry tear arising directly from a proximal anastomosis performed with the Heartstring hemostatic seal system.
