Translocation of the Aortic Valve in a Patient with Calcified Aortic Valvular Stenosis and Unstable Angina / 日本心臓血管外科学会雑誌

ABSTRACT

A 64-year-old woman with a diagnosis of calcified aortic valvular stenosis and unstable angina, had calcification of the aortic valve reaching the aortic annulus, and the ascending aorta had some calcifications in its lateral and posterior walls. There was a 70mmHg pressure gradient in the aortic valve and coronary angiogram showed 90% stenosis of right coronary artery #1 and total occlusion of left circumflex artery #13 perfused with collateral flow from right coronary artery. The translocation of the aortic valve was carried out. The postoperative course was uneventful and postoperative angiograms showed good patency of the double saphenous vein grafts and no abnormality of the composite graft anastomosis. Translocation of the aortic valve is effective in patients with stenotic aortic annulus caused by calcified aortic valve, although it is mainly indicated in infective endocarditis.
