We describe a 77-year-old woman with severe aortic stenosis, porcelain aorta and coronary artery disease, who underwent apicoaortic bypass with coronary artery bypass grafting. The patient, who had a history of aortitis syndrome had dyspnea. Cardiac echocardiography showed severe aortic valve stenosis（aortic valve pressure gradient（max/mean)＝115/74.4mmHg, aortic valve area＝0.48cm2). Coronary angiography showed severe stenosis of right coronary artery orifice（#1.90%）. Computed tomography showed severe calcification of the thoracic aorta and surgical manipulation for ascending aorta was impossible. We did not perform ordinary aortic valve replacement. Instead, apicoaortic bypass with coronary artery bypass grafting was performed. We approached by a left anterolateral thoracotomy at the 6th intercostal level. Apicoaortic valved conduit（valved graft:Edwards Prima Plus Stentless Porcine Bioprosthesis 19mm＋UBE woven graft 16mm）was implanted. Saphenous vein graft was harvested and coronary bypass grafting（valved conduit-#4AV）was performed in the same operative field. Postoperative cine MRI showed that most of the cardiac stroke volume flowed through the conduit（44.4ml/beat, 92.3%), with the flow via the aortic valve accounting for 3.69ml/beat, 7.7%. Postoperative enhanced CT showed that the coronary artery bypass graft was patent. Apicoaortic bypass is a good surgical option for aortic stenosis with severe calcification aorta and coronary artery bypass grafting can also be performed in the same view.
