Reverse-U Aortotomy (Kırali Incision) for Aortic Valvular Interventions

Abstract

Background Surgical incisional approach to the ascending aorta is the main strategic step during valvular and/or subvalvular aortic interventions. Classic aortotomy incisions (transverse or oblique) can be challenging and can cause suboptimal exposure of the aortic root especially for the patients with small aortic annulus or for redo coronary artery bypass patients with patent proximal grafts interposed to the ascending aorta.

Methods The Kırali incision was used in 91 patients (including 13 reoperations) who underwent an aortic intervention for valvular and subvalvular pathologies. Aortic root was exposed by forming inverted “U” shape incision starting from approximately 3 cm above the right coronary ostium toward the center of the noncoronary annulus and the top of the left–right commissure like a tongue.

Results The aortic valve was replaced with a mechanical prosthesis in 45 patients and with a bioprosthesis in 39 patients including 14 sutureless and 16 stentless prostheses. A total of 29 patients received a concomitant procedure per the following: coronary artery bypass grafting on 8 patients and left ventricular assist device on 7 patients. There was no any problem related to aortotomy incision technique such as bleeding, rupture, dehiscence, or laceration perioperatively. There was no complication related to the procedure during 5-year follow-up.

Conclusion This new aortotomy incision technique is a safe procedure that provides good exposure for all kinds of aortic valve interventions and protects grafts and can facilitate aortic root enlargement or aortoplasty easily. This incision has the potential to be an alternative to traditional techniques.
