Early Non-Invasive Angiographic Results of the “Button Inside” Technique for the Reattachment of Coronary Arteries in the Aortic Root Replacement

Background and Aim: The Button technique was the operative technique generally used for the reimplantation of coro- nary arteries in the aortic root replacement because of reduced anastomotic complications respect to the original wrapped operation described by Bentall and De Bono. The “Button Inside” technique is a modified Button technique recently performed in all consecutive series of patients operated on aortic root replacement at our Institution. In this study we report early postoperative angiographic results of patients operated on aortic root replacement using the “But- ton Inside” technique. Methods: Magnetic Resonance Imaging angiography was achieved in all patients operated on aortic root replacement. Morphological characteristics of the site of coronary buttons reattachment were accurately evaluated. Results: No postoperative anastomotic leakages were detected at the site of coronary buttons anastomosis. Moreover, in this first series of postoperative control aneurisms of coronary buttons were not detected. Conclusions: Early postoperative non-invasive angiographic results of the “Button Inside” technique are encouraging. This surgical approach for the reattachment of coronary arteries is suggested in aortic root replacement when is possible to mobilize coronary arteries in order to reduce coronary artery anastomotic complications.
