Résumé : Aortic stenosis is the most important acquired heart disease, with a prevalence of 4.8% in patients aged more than 75 years and represent more than 60% of the indications for cardiac surgery in elderly patients. Regardless of the good results reported with conventional aortic valve replacements (AVRs) in elderly patients, still many patients are denied surgery by the high operative risk. In this frail population, Transcatheter Aortic Valve Implantation (TAVI) can be a good compromise to achieve good results and minimize morbidity and mortality. This technique allows implanting a balloon-expandable bioprosthesis, without resecting the native aortic valve. Several complications are described as consequence of the residual, highly calcified valve squeezed between the aortic wall and the stent of the implant. In this perspective, the concept of endovascular resection of the aortic valve, before TAVI, was developed and enhanced by Astarci, Glineur, Elkhoury, and Raucent.
