Figure 1. Preoperative assessment before aortic valve replacement in a 55-year-old man with a history of congenital bicuspid aortic valve and aortic stenosis. Coronal volume-rendered image shows a small amount of calcium at the level of the aortic valve (lower arrow). The ascending aorta is free of atherosclerotic disease (upper arrow). Direct aortic cannulation can be performed safely.
