Transcatheter Aortic Valve Implantation: Upcoming New Devices

Transcatheter aortic valve implantation (TAVI) is an alternative to surgical aortic valve replacement in high-risk patients with symptomatic severe aortic stenosis. Several upcoming devices will optimize and facilitate the procedure: periprosthetic aortic regurgitation will be reduced by larger prosthesis sizes and repositionable next-generation transcatheter heart valves. Alternative access routes and smaller sheaths will reduce the rate of vascular complications. Cerebral protection devices might reduce the rate of strokes and silent cerebral embolism. Abandonment of balloon valvuloplasty and rapid ventricular pacing might facilitate the procedure and improve outcome. Thus, younger and healthier patients could benefit from TAVI in the near future.
