An Interventional Odyssey: The Importance of Planning and Prompt Recognition and Treatment of Complications During a Complex Chronic Total Occlusion Intervention.

Despite significant progress, chronic total occlusion (CTO) percutaneous coronary interventions (PCI) are often challenging and carry increased risk of complications. We present a highly complex CTO PCI case that was successfully completed despite numerous complications (perforation, donor vessel closure, stent loss, guide extension tip fracture, access site bleeding and cardiac arrest) to highlight the importance of appropriate patient selection, pre-procedural planning, comprehensive patient-centered risk/benefit discussion, and prompt recognition and treatment of intra-procedural complications.
