Chronic Total Occlusion (CTO)

Chronic Total Occlusion (CTO) remains one of the most technically challenging areas in interventional cardiology. This session provides an in-depth exploration of anatomy, lesion characteristics, procedural planning, and advanced revascularization strategies essential for successful CTO PCI. As interventionalists frequently search for a dedicated cardiology conference, this session emphasizes practical tools for improving procedural success while minimizing complications.

The description addresses lesion morphology, J-CTO scoring, wire strategies, antegrade and retrograde approaches, dissection-reentry techniques, microcatheter selection, and intravascular imaging. Participants will learn to analyze angiographic projections, understand collateral channel selection, and navigate complex anatomy. Case-based demonstrations highlight decision pathways, bailout strategies, radiation reduction techniques, and complication management.

A major theme focuses on applying advanced CTO PCI strategies to appropriate patients. Attendees will review indications, ischemic burden assessment, viability imaging, shared decision-making, and long-term outcome data. The session explores hybrid algorithms, operator skill development, and team-based approaches that combine imaging specialists, support staff, and high-volume operators.

Future discussions include robotic CTO PCI, AI-guided route planning, improved re-entry tools, and next-generation wires and microcatheters. By the end, participants will gain confidence in evaluating CTO lesions and executing successful, safe revascularization.
