Composite graft replacement in acute aortic dissection: technique for anastomosing the right coronary artery without...

Acute aortic dissection that involves the ostium of the right coronary artery is a rare occurrence, but treatment by composite graft replacement of the aortic root is a technically difficult procedure, usually involving implantation of an aortic button. We describe 2 patients with ostium of the right coronary artery severely damaged by acute aortic dissection. In both cases we used a technique that mobilized the right coronary artery sufficiently so that it could be implanted without including an aortic button.
