With the development of transcatheter aortic valve replacement, it has become the first-line treatment for elderly patients with aortic valve stenosis. A case of transcatheter aortic valve replacement in a patient at high risk of coronary artery occlusion was reported. The use of intravascular ultrasound to observe the spatial relationship between the coronary ostia and the valve was the characteristic of this case. This patient was an elderly male who was assessed as a high risk of acute coronary artery occlusion before transcatheter aortic valve replacement. After fully evaluation of the patient’s surgical risks\benefits, the strategy was formulated. Percutaneous coronary intervention was the first step. At the same time, intravascular ultrasound was used to observe the spatial relationship between the coronary ostia and the valve, and balloon was embedded for coronary protection. The procedure went smoothly.
