In 2002, the first transcatheter aortic valve implantation was performed by Dr. Alain Cribier <cite>Cribier</cite>. A transcatheter aortic valve implantation is a less invasive treatment option for patients at prohibitive risk for conventional aortic valve replacement. In this technique, the native valve is not excised. After balloon valvuloplasty, the prosthetic valve is implanted in the aortic position, with the frame of the prosthesis covering the native valve. The bioprosthesis can be implanted retrograde or antegrade. Currently 4 different approaches may be used in this technique. (table…). Transcatheter aortic valve implantation is assessed in randomized clinical trials and registries. | |||
