Abstract

Balloon and microcatheter uncrossable chronic total occlusions can be challenging to treat. We present a novel technique for treating such lesions through contrast injection via a guide catheter extension wedged against the proximal cap. We named this technique "guide-extension Carlino."

Keywords: atherosclerosis; chronic total occlusion; coronary circulation; percutaneous coronary intervention.
