[Transcatheter aortic valve implantation: Present and development trend].

Currently, although surgical aortic valve replacement (SAVR) is still the golden standard in treatment of severe aortic stenosis according to the guideline, transcatheter aortic valve implantation (TAVI) is gradually becoming a common treatment for patients who are prohibitive or in high risk for SAVR. Recently, the valve manufacturers, including medical companies in China, are making their utmost to develop valve device, leading remarkable results achieved by TAVI. With the complications being controlled, TAVI displays promising future. It is likely that TAVI is expected to become a substitute for SAVR to treat patients with aortic stenosis or even aortic regurgitation.
