Management of the atherosclerotic ascending aorta with endoaortic occlusion.

Application of an external cross-clamp to an atherosclerotic ascending aorta increases the risk of an embolic event and traumatic injury of the aorta. Currently, there are limited management options in these patients when the clinical situation requires cardiac arrest during an operation. We present our approach to these patients using the Heartport Endoaortic Clamp (Heartport, Redwood City, CA).
