Abstract:
We report a case of aortic valve replacement and hemiarch replacement with reconstruction of the brachiocephalic artery in a patient with a porcelain aorta. A 65-year-old man was admitted to the hospital for aortic stenosis. Computed tomography demonstrated severe aortic calcification and extensive calcification covering a wide area of the aorta. The echocardiography showed a highly calcified aortic valve and a pressure gradient of 109 mmHg across the aortic valve. At surgery, calcification of the ascending aorta was severe and involved its entire circumference. Therefore, 2 cannulae were inserted to the right axillary and right femoral arteries for extracorporeal circulation. We performed replacement of the ascending aorta and hemiarch with reconstruction of the brachiocephalic artery under circulatory arrest and antegrade cerebral perfusion, as well as aortic valve replacement with a 21 mm St. Jude Medical mechanical valve. He had no major cardiac complications during the postoperative course, and was discharged on postoperative day 33.
