Bilateral percutaneous ulnar artery approach for retrograde chronic total occlusion intervention.

The transradial approach for coronary diagnostic and therapeutic interventions is a well-established, safe, and effective technique that has shown a success rate comparable to that of the transfemoral approach for chronic total occlusion (CTO) with less access site complications. Recently, the transulnar approach was also found to be a safe and feasible alternative for diagnostic and percutaneous coronary intervention (PCI). There is limited data on the efficacy and safety of the transulnar approach for CTO PCI. Here, we report the case of a patient who underwent coronary intervention for CTO via the bilateral ulnar approach.
