The Ulnar Artery as a Favorable Primary or Alternative Access Site for Coronary Angiography and Interventions.

The transulnar approach (TUA) has been considered both as primary access and as a secondary access site after transradial access (TRA) failure for coronary invasive procedures. However, there is little evidence supporting the use of the TUA as the first approach to diagnostic coronary angiography (CAG) or interventions. Patients (n = 587) who underwent CAG and/or angioplasty (292 patients via TRA, 295 patients via TUA) were included.
