Antegrade rewiring of the retrograde Corsair catheter during revascularization of chronic total coronary occlusions: a simple alternative to guidewire exteriorization.

Chronic total occlusions prevent a significant challenge to interventional cardiologists. Successful opening of chronically occluded vessels has been shown to be associated with decreased mortality and morbidity. Recently, the retrograde approach to chronic total occlusion intervention has been developed. In this case series, we present a novel technique to assist with this procedure involving antegrade wiring of a retrograde microcatheter.
