Résumé
Traditionally, the transcatheter aortic valve replacement is performed through a transapical, a transfemoral or a trans-subclavian approach. Recently, the transaortic approach for transcatheter aortic valve replacement through the distal part of the ascending aorta was successfully implemented in order to avoid peripheral vascular access-related complications and apical life-threatening haemorrhage. The Sapien? stent valve has great transaortic potential because it can be loaded 'upside down' in different generations of delivery systems. However, because of their health regulatory systems and despite the launch, in 2012, of the latest generation of the Ascendra? delivery system, the Ascendra+?, specifically designed for transapical and transaortic valve placements, several countries are still using the first generations of Ascendra? (Ascendra? 1 and 2). This device was specifically designed for transapical procedures, and retrograde stent-valve positioning through the stenotic aortic valve may be very challenging and risk the integrity of the aorta. We describe the manoeuvre required in order to pass the stenotic aortic valve safely in a retrograde direction using the Sapien? stent valve and the first generations of Ascendra?.
