We report our experience using transradial access (TRA) for carotid artery stenting (CAS). Eighty-eight patients underwent CAS using a nonfemoral approach, 79 of them by TRA. Carotid artery stenting was performed using standard techniques with a long hydrophilic sheath. Mean age was 69.5 years. A total of 46 patients were symptomatic and 34 were asymptomatic. Transradial access and procedural success were achieved in 98.8% and 96.6% of the cases, respectively. There were no deaths, myocardial infarction, or radial access site complications. In all, 2 patients sustained a stroke, 1 hemorrhage, and 1 ischemia. Carotid artery stenting using TRA was safe and technically feasible.

The TR approach for CAS is safe and efficacious, with acceptable cross-over rate. In both groups, vascular complications rarely occurred.

Background and Aim. Conduction disturbances leading to permanent pacemaker implantation (PPMI) remains a common complication for TAVR procedures, particularly when self-expanding valves are used. We compared the 30-day incidence of new-onset left bundle branch block (LBBB) and permanent pacemaker implantation (PPMI) rate between two consecutive groups using either conventional 3-cusp coplanar view (CON) and right/left cusp-overlap view (COVL) for implantation. Methods and Results. We retrospectively compared 257 consecutive patients undergoing TAVR with self-expandable valves using either CON (n = 101) or COVL (n = 156) in four intermediate/low volume centers. There were no significant differences in baseline characteristics between the groups. The 30-day incidence of new-onset LBBB (12.9% vs. 5.8%; p = 0.05 ) and PPMI rate (17.8% vs. 6.4%; p = 0.004 ) was significantly lower when using the COVL implantation view. There was no difference between the CON and COVL groups in 30-day incidence of death (4.9% vs. 2.6%), any stroke (0% vs. 0.6%), and the need for surgical aortic valve replacement (0% for both groups). Conclusion. Using the COVL view for implantation, we achieved a significant reduction of the LBBB and PPMI rate after TAVR in comparison with the traditional CON view, without compromising the TAVR outcomes when using self-expandable prostheses.
