Objectives: The equipment and strategies used for percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) have been improved. However, CTO-PCI for patients with prior coronary artery bypass graft (CABG) remains challenging. This study aimed to compare the strategies and initial success rates of CTO-PCI in patients with and without prior CABG.

For proximal cap ambiguity, the Global CTO consensus group uses the "anatomy dictates strategy" method: 1) intravascular ultrasound; 2) move the cap; or 3) retrograde. For CTO body crossing, anatomy dictates 4 strategies: 1) CTOs with tapered stump-loose tissue tracking; 2) CTOs with clear intimal path-intentional intimal tracking with 3-dimensional (3D) wiring; 3) CTOs without a clear intimal path-intentional intimal tracking with intermediate penetration wire; and 4) the "long plus CTOs"-intentional subintimal wiring.

Objectives: This study aimed to assess the technical aspects and outcomes of percutaneous coronary intervention (PCI) in patients with aorto-ostial chronic total occlusion (CTO).
