Traditional Versus Distal Radial Access for Coronary Diagnostic and Revascularization Procedures: Final Results of the TENDERA Multicenter, Randomized Controlled Study.

Background: Traditional transradial access (TRA) is widely used for coronary and non-coronary interventions with significant improvements in procedural outcomes; however, it is associated with RAO that precludes repeat use of the same artery for possible future TRI and other purposes. Distal radial access (DRA) has been proposed as an effective alternative to decrease RAO rates. Published literature describing the RAO rate after DRA versus TRA from various RCT and clinical registries has shown conflicting results.
