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.
View Article and Find Full Text PDFAntegrade wiring (AW) is the prevailing chronic total occlusion (CTO) crossing technique. 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.

- The study investigates the long-term effectiveness of a treatment method (directional coronary atherectomy followed by drug-coated balloon angioplasty) for large bifurcation lesions, especially those affecting the left main trunk.
- It analyzed 129 cases, primarily involving left main trunk lesions, and measured outcomes like target lesion revascularization and adverse events over a follow-up period averaging 53.4 months.
- Results showed low rates of target lesion revascularization and other adverse events at 24 and 36 months, suggesting that this treatment is a viable option for managing complex coronary conditions.
Background: PCI for aorto-ostial CTO remains challenging. The techniques for guidewire in aorto-ostial CTO may differ from those used in non-aorto-ostial CTOs, influenced by clinical and angiographic characteristics.
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).
Article Synopsis
- * The primary outcome was target lesion revascularization (TLR), which occurred in 4.8% of patients, and the secondary outcome was major adverse cardiac and cerebrovascular events (MACCEs), occurring in 14.3%.
- * Key risk factors for TLR included in-stent occlusion, hemodialysis, and diabetes mellitus, while MACCEs were notably associated with hemodialysis and arteriosclerosis obliterans, highlighting the
