**Abstract**

Since the successful application of transcatheter aortic valve implantation (TAVI) in 2002, the interventional treatment of valvular heart disease has developed rapidly. The interventional treatment of aortic valve stenosis or insufficiency has been more mature, and many new-generation TAVI valves have been developed. The recommended level of TAVI technology in the European and American heart valve disease guidelines has increased year by year. In 2019, the multi-center randomized controlled study on patients with low-risk aortic stenosis and conventional aortic valve replacement also showed the advantages of interventional treatment technology, such as small trauma, fast recovery and less complications, and better hemodynamics, which greatly promoted the development of TAVI technology.
