Total wrist access for angiography and interventions: Procedural success and access site crossover in a high volume transradial center.

•Total wrist access can be implemented safely in experienced transradial centers.•This is an observational study with a large patient cohort.•Failure of transradial access is caused by failure to puncture, presence of RA anomalies, high grade spasm or RA occlusion.•Pre-procedural radial artery angiography provides a roadmap for successful arterial access.•Total wrist access is feasible and safe with low percentage of access site complications
