We report an 84-year-old woman diagnosed with aortic stenosis and regurgitation with a severely calcified narrow aortic root and left main coronary artery trunk stenosis with triple-vessel coronary artery disease. Emergency aortic valve replacement and triple coronary artery bypass grafting were successful. The aortic annulus was small and heavily calcified, and the ascending aorta, the sinus of valsalva and the anterior leaflet of the mitral valve were severely calcified. A St. Jude Medical valve 19A (St. Jude Medical Inc., St. Paul, MN) was inserted obliquely along the noncoronary sinus. This technique is a useful alternative in cases where the patient's life is at risk in situations involving severe extensive calcification of a narrow aortic root.
