Translocation of the aortic valve for aortic stenosis in a patient with severe calcification in the aortic root: report of a case

A 65-year-old woman was admitted to the hospital because of anterior chest pain. Computed tomography and transthoracic 2-D echocardiogram demonstrated aortic valvular stenosis with calcification of whole aortic root. Cardiac catheterization study showed a transaortic pressure gradient of 73 mmHg and coronary angiography showed 75% stenosis at the right coronary ostia. Aortic valve replacement and coronary artery bypass grafting were planned. At operation, sinotubular junction and bilateral coronary ostia severely calcified with stenosis, prompted us to translocate the aortic valve with the composite graft, a 19 mm Bicarbon prosthesis and 25 mm woven Dacron graft. The postoperative course was uneventful. On cardiac catheterization done 27 days after operation, satisfactory valve motion and patent coronary bypass grafts were confirmed.
