The percutaneous aortic valve replacement (TAVI) is the most recent and promising procedure in the area of interventional cardiology with a rapidly growing number of interventions worldwide. The transfemoral approach being less invasive, it has become the predominant access for the device delivery. The prevention of vascular complications by an optimal risk stratification using appropriate imaging techniques (vascular CT scan and angiography), optimised techniques for femoral puncture (active control of the arterial punction, crossover...) and skilled teams for peripheral angioplasty and percutaneous arterial closure devices (Prostar) has become mandatory given the fragile target population for TAVI. Vascular complications remain indeed one of the most frequent complication although the trend toward reduced sheeths size led to significant reduction This is mandatory regarding the needed size of the vascular arterial access - itself with constant improvement by minimising the initial 24 French with mandatory real chirurgical closure to the actual 18-19 French and soon 16 French. The improvement of the implanted devices is due to the recent evidence of the promising future of this technique and the important technological effort realised by the industry not only on the implanted aortic prosthesis but also on their delivering catheters.
