Abstract

|
A 32-year-old woman diagnosed with Turner syndrome presented to the hospital for an evaluation of cardiovascular complications. Preoperative computed tomography (CT) and echocardiography showed progression of aortic root and ascending aorta dilatation, as well as a bicuspid aortic valve. There was no evidence of aortic regurgitation. We planned valve-sparing aortic root replacement and ascending aorta replacement with a high risk of aortic rupture. Intraoperatively, we incidentally found a juxtacommissural origin of the right coronary artery (RCA). We performed aortic valve reimplantation using a graft designed with a key-shaped hole to wrap the juxtacommissural-origin RCA by modifying the Florida sleeve technique. Coronary blood flow was patent on postoperative CT angiography, and there was no evidence of aortic regurgitation on postoperative echocardiography. The patient was discharged from the hospital on postoperative day 7 without any complications.
