Balloon-uncrossable chronic total occlusion (CTO) lesions remain a major cause of procedural failure with increased contrast use, radiation exposure and adverse outcomes. Effective management requires a structured escalation strategy. Initial steps focus on support optimization with large-bore guides, guide extensions, and anchoring techniques. If unsuccessful, operators advance to torqueable or low-profile microcatheters, downsized balloons, or balloon-assisted microdissection. Resistant lesions often necessitate plaque modification with excimer laser or rotational/orbital atherectomy. Subintimal approaches, including external crush and distal anchoring, serve as last-line options. By following a structured escalation pathway, operators can maintain high procedural success while minimizing complications in this complex subgroup.
