TAVI is a new technology for the patients who cannot receive the routine surgical aortic valve replacement under cardiopulmonary bypass.Vascular access is also a key point to success of TAVI,beside the selection of indication.Presently,the available vascular access mainly includes:antegrade approach,retrograde approach,transapical approach,trans-subclavian approach,and direct trans-aortic approach.Trans-femoral approach is the dominant TAVI route; however,each of them has their advantages and disadvantages.Selection of vascular approach depends on the conditions of patient’s arteries and aortic root.In this study,selective principle,complications,surgical methods and the latest clinical research of each vascular approach are reviewed,in order to develop this technology in China.
