ABSTRACT

Percutaneous coronary intervention (PCI) for chronic total occlusions (CTO) in patients with prior coronary artery bypass graft surgery is among the most challenging scenarios in interventional cardiology. These patients commonly present with anatomically complex lesions, characterized by ambiguous proximal caps, severe calcification, and long occlusion lengths. Advances in procedural techniques, particularly the hybrid algorithm, have helped improve procedural success and reduced complications. Nevertheless, successful CTO PCI in this population has been shown to improve anginal symptoms and quality of life, despite a higher risk of long-term cardiovascular events due to pre-existing comorbidities and advanced coronary artery disease.
