Patients with severe aortic stenosis (AS) who are ineligible for surgery due to technical/anatomical complications or significant surgical risk can now get transcatheter aortic valve implantation (TAVI), a fast-developing therapeutic option. When practical, the transfemoral technique is the preferred TAVI delivery method. Transaortic, trans-subclavian, and transapical access are other non-transfemoral access possibilities. The transcarotid, transcaval, and antegrade aortic methods are also viable, although they are only available to experienced surgeons and medical facilities. It is essential to thoroughly evaluate the patient's atherosclerotic load and location, arterial size and tortuosity, and the presence of mural thrombus due to the unique characteristics of each vascular approach created for TAVI delivery. Several clinical trials are presently being conducted, and in the near future, it is anticipated that the indications for these methods will be clarified and expanded to a wider range of TAVI candidates.
