ABSTRACT
OBJECTIVE:
This study sought to assess the potential benefits of the transradial approach (TRA) as an alternative vascular access to the classical contralateral femoral approach for transcatheter aortic valve replacement (TAVR).BACKGROUND:
Vascular and bleeding complications in TAVR have gradually decreased owing to operator experience and downsizing of the delivery system. However, about 1/4 of vascular access site complications are related to the transfemoral (TF) secondary access.METHODS:
We compared the outcomes at 30 days according to VARC-2 after TAVR of a prospective cohort of 217 consecutive patients undergoing right or left TRA as the second vascular access (TRA-TF TAVR) and a retrospective cohort of 194 consecutive patients undergoing TF approach as a second vascular access (TF-TF TAVR).RESULTS:
Baseline clinical characteristics and risk scores were well matched in both groups. Procedural success rate was 99.7%. Fluoro time was significantly lower in the TF-TF TAVR group (16.9 ± 7.2 vs. 19.1 ± 7.8 min, P = 0.003); however, there was no significant difference in x-ray exposure, procedure time or amount of contrast used. In the TRA-TF TAVR group, there were no complications related to the TRA access and there were less vascular and bleeding complications (18.0% vs. 9.7%, P = 0.014; 17.0% vs. 9.2%, P = 0.026, respectively), although blood transfusion requirement or hospitalization duration stay were similar in both groups.CONCLUSIONS:
TRA approach as alternative secondary vascular access in TAVR is safe and feasible and is associated with a significant decrease in vascular and bleeding complications. Further, large-scale studies are warranted to confirm the potential benefit of this approach.Palabras clave
