    Abstract:
    BACKGROUND: Vascular complications from transfemoral (TF) secondary access during transcatheter aortic valve implantation (TAVI) are common. We compare our experience of transradial (TR) versus transfemoral secondary access during TAVI and describe techniques for performing iliofemoral arterial intervention from the transradial approach. METHODS: All TAVI procedures with a single secondary access were included. Demographics, procedural details and 30-day outcomes were recorded. VARC-2 criteria were used for procedural complications. Procedures with TF primary access were stratified by the site of secondary arterial access. RESULTS: Single secondary access was used in 199 cases, of which 20 were performed via non-TF access. Of the 179 TF primary access cases, 115 (64%) used TR secondary access and 64 (36%) used TF secondary access. In the TR cohort percutaneous vascular intervention was performed from the transradial approach in 19 cases (17%). Emergent TF secondary access was not required in any case. There were no differences in procedural time, radiation dose, contrast use, bleeding complications, stroke or mortality between the groups. There was one secondary access complication in the TF cohort and none in the TR cohort. CONCLUSIONS: Transradial (TR) secondary access during TAVI is safe and feasible and may reduce the secondary access site vascular complication rate. With appropriate equipment, most peripheral vascular complications can be managed entirely via TR access avoiding unplanned femoral arterial access. TR secondary access should be considered the default approach for non-TF TAVI cases and can be considered for all TF cases as long as dedicated equipment is available.
