*6.1.4.1 Implantation techniques*

TAVI is currently carried out using two main approaches, **transfemoral** and **transapical**. If this is not feasible, then the other two main approaches could be used namely trans-axillary artery or transaortic approaches. It is, therefore, highly recommended to perform an adequate preoperative assessment of the degree of peripheral arterial disease through imaging studies such as CT.
