[Transcatheter aortic valve replacement].
After more than ten years of development, A. Cribier accomplished in 2002 the first percutaneous aortic valve replacement (AVR), which is a curative procedure for severe aortic stenosis and an alternative to surgery for high risk patients. With material improvements over time, the procedure has evolved to become a purely percutaneous intervention in most centers. Currently, two different valve systems, the CoreValve Revalving system and the Edwards SAPIEN valve, have each been implanted in more than 1,500 patients. Careful patient selection, including consideration of vascular access, associated cardiomyopathies and annulus size, remains critical. Although this technique has generated great enthusiasm, conventional surgery remains the gold standard in late 2008.
