Initial Experience With the Gaia Composite Core Guidewires in Coronary Chronic Total Occlusion Crossing.

ABSTRACT

Inability to cross the occlusion with a guidewire is the most common cause of failure of coronary chronic total occlusion (CTO) interventions. We describe two cases of successful application of the novel Gaia family of coronary guidewires (Asahi Intecc) for crossing coronary CTOs using all available crossing strategies, namely antegrade wire escalation, antegrade dissection/reentry, and retrograde.
