This paper reports a case of severe stenosis and calcification of functional bicuspid aortic valve treated with transcatheter aortic valve replacement (TAVR). Before the operation, echocardiography and multi-detector computed tomography were used to evaluate the ascending aorta, coronary artery, iliac artery anatomy, valve morphology, and valve calcification. During the operation, femoral artery perforation occurred after suturing the puncture site. The treatment of compression and hemostasis with peripheral balloon was performed. After the operation, neuropsychiatric symptoms appeared. The result of brain MRI indicated multiple acute cerebral infarction. Anticoagulant, antiplatelet, and neurotrophic drugs were used. After 1-year follow-up, echocardiography showed a little reflux signal around the artificial aortic valve, and the patient’s nervous system examination showed no obvious abnormality. TAVR indications will continue to expand in the near future with the innovation of evaluation, devices, and technology. The summary of operation data can promote progress of TAVR and reduce the occurrence of complications.
