Introduction
Acute DeBakey type I aortic dissections frequently present symptomatically at the time of dissection onset and have been associated with risks of aortic rupture, acute severe aortic regurgitation, and/or cardiac tamponade1,2. Classically, the treatment for an acute DeBakey type I aortic dissection is with an open surgical repair with an ascending aortic replacement, hemiarch replacement, zone 1 arch, zone 2 arch, and/or total arch replacement. The various approaches for this operation3, are balanced with the severity of presentation, immediate mortality risk, facility resources, and surgeon preference. We herein present one of first reports of Cor-Knot automated fastener utilization in aortic arch surgery. Institutional Review Board approval was waived, and informed consent was obtained.
