Transcatheter aortic valve replacement is an effective treatment for aortic stenosis currently, especially in elderly, surgical high-risk, and surgical procedures-intolerant patients with severe aortic stenosis. After several generations of updates in design and function, the self-expandable valves have shown significant efficacy in treating aortic stenosis patients with bicuspid aortic valve, bioprosthetic valve failure or small annulus, and superiority in terms of valve durability, and the favorable hemodynamic outcomes could translate into clinical endpoint benefit. This literature review summarizes the advantages and recent advances of the self-expandable valves in transcatheter aortic valve replacement.
