[Percutaneous aortic aortic valve replacement: myth or reality?].
Aortic valve replacement with mechanical or biological prosthesis with extracorporeal circulation is the gold-standard for the treatment of calcific aortic stenosis. Although the results are excellent with the conventional approach some elderly patients, with multiple high-risk comorbid conditions, reoperations and severe left ventricular dysfunction have high surgical risk. During the last years percutaneous techniques have been developed. The present study aim to analyse the literature, since the experimental development until clinical application of this novel treatment in patients with high surgical risk aortic stenosis. Percutaneous implantation of aortic valve prosthesis is being done in some centers and the cardiovascular surgeon that treats valve disease should be involved in this development.
