Objective:To improve the understanding of clinicians on transcatheter aortic valve replacement(TAVR). Methods:The di-agnosis and treatment course and intraoperative image data of a patient with TAVR surgery were reported. The indications,artificial valves,surgical complications and prospects were discussed through literature review. Results:The patient was hospitalized for heart failure. The echocardiography indicated severe aortic stenosis;conservative treatment was not effective,and the risk of surgical opera-tion was high,so TAVR was choose. After TAVR,the heart failure symptoms disappeared,and echocardiography showed significant decrease in aortic valve differential pressure. The left ventricular diameter decreased significantly 3 months after surgery. Conclusion:TAVR surgery is less traumatic and patients recover quickly. TAVR surgery has become a choice for severe aortic stenosis patients with middle-high risk of surgery.
