Abstract:
We reported simple partial root remodeling using a graft trimmed twin "U" shape for extensive dissection into the right/non-coronary sinuses with acute type A aortic dissection with cardiac tamponade, acute myocardial infarction on the right coronary artery and aortic regurgitation. After total arch replacement with frozen elephant trunk technique for distal dissection, partial root remodeling on the non and right coronary sinuses was performed. Postoperative computed tomography (CT) showed well shaped Valsalva sinuses and aortic regurgitation completely disappeared. This technique might become an alternative procedure for aortic dissection severely involving Valsalva sinuses without dilatation on the aortic root.
