| Popis: | Surgical aortic valve replacement remains the gold standard for the treatment of severe, symptomatic aortic stenosis. However, percutaneous treatments are challenging this paradigm in high-risk surgical patients. Technological developments have been rapid in the field of percutaneous aortic valve intervention. Two devices have been approved for general use in Europe: the Edwards SAPIEN valve (Edwards Lifesciences, Irvine, CA) and the CoreValve ReValving((R)) System (CoreValve ReValving((R)) Technology Medtronic Inc., Minneapolis, MN), with 15 potential new designs for percutaneous aortic valves in development around the world. Both systems can be delivered via the transfemoral, transapical and the axillary/subclavian routes, depending upon patient characteristics, anatomy, and the device available to the operator. Careful selection of appropriate patients is essential to ensure a safe procedure. This necessitates a multidisciplinary approach, with multiple imaging modalities used to fully delineate the peripheral vasculature, aortic anatomy and the valve itself. It is important to remember, however, that just because we can treat aortic valve disease percutaneously, it does not mean that we necessarily should. The gold standard treatment for aortic stenosis remains thoracotomy and surgical replacement of the valve; to this end it is essential that surgeons play a central role in the decision-making processes for transcatheter aortic valve implantation and that they embrace this new and exciting technology, which promises to dramatically change the way their high-risk aortic valve patients are managed over the course of the next 10 years. |
