“Investment technique” for improving recanalization of a coronary chronic total occlusion with conventional and drug-coated balloons: the IMPROVED–CTO registry

Abstract

Chronic total occlusion plaque modification (CTO-PM) is often used after unsuccessful CTO interventions to facilitate future attempts. We aimed to explore the safety and efficacy of both conventional (CB) and drug-coated balloons (DCB) for CTO-PM.
