Summary
Chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has been rapidly evolving with high success and acceptable complication rates currently being achieved at dedicated high-volume centers. Successful CTO PCI in appropriately selected patients can provide significant clinical benefits, however crossing the occlusion with a guidewire can be challenging. The following techniques can be used for CTO crossing: antegrade wire escalation, antegrade dissection/re-entry and the retrograde approach. Antegrade wire escalation remains the most frequently used technique and is the most common final successful technique, especially in less complex CTOs. Antegrade dissection re-entry and the retrograde approach are more technically demanding, but are often necessary to achieve crossing, in complex CTOs. In this manuscript, we provide a comprehensive overview of antegrade wire crossing of coronary CTOs.
