Mechanical assist device for right ventricular failure after acute aortic dissection.

Acute myocardial ischemia and infarction due to retrograde coronary artery dissection are uncommon complications after ascending aortic dissection. A case of acute aortic dissection with massive right ventricular failure successfully treated by replacement of the ascending aorta and postoperative right ventricular mechanical support is presented. Although mechanical assistance may be hazardous after ascending aortic replacement, because of the need of anticoagulation, it represents a valid therapeutic option when severe right ventricular failure due to acute myocardial infarction ensues.
