Transcatheter aortic valve replacement（TAVR）：The first case in Chongqing and review of literature

Abstract:

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.
