The short-term mortality of patients with severe aortic stenosis is high, which presents a great challenge to clinical treatment. With the development of transcatheter aortic valve replacement (TAVR), emergent TAVR brings hope for the treatment of these patients. We present here a case of emergent TAVR procedure. The patient was an elderly male who had previously undergone surgical mitral valve replacement. After fully assessing the risk/benefit of TAVR procedure, emergent TAVR was performed for the patient. The patient was in good condition at two-month follow-up. Emergent TAVR is a good option for critical high-risk patients with severe aortic stenosis.
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.
