Antegrade Chronic Total Occlusion Crossing

Antegrade Techniques for Chronic Total Occlusions

By convention, a total obstruction of the coronary artery with no flow at the occluded segment that has been present for at least 3 months is termed as chronic total occlusion or CTO. This is to be distinguished from a sudden occlusion of the coronary artery lumen by a thrombus during an acute myocardial infarction. Percutaneous coronary intervention (PCI) of CTO is increasingly being performed...

Reverse Controlled Antegrade and Retrograde Subintimal Tracking in Chronic Total Occlusion of Right Coronary Artery

Passage failure of guidewire is still remained most common reason for percutaneous coronary intervention (PCI) failure in chronic total occlusion (CTO). Intravascular ultrasound study (IVUS) and cardiac CT angiography can help identify features that most influence current success rates of PCI. We report our experience using the reverse controlled antegrade and retrograde subintimal tracking tec...

Antegrade Dissection and Reentry as Part of the Hybrid Chronic Total Occlusion Revascularization Strategy

Editorial Chronic Coronary Total Occlusion

Chronic total occlusion (CTO) is quite frequent finding in coronary artery disease. Comprised of a combination of fibrocalcific and thrombotic elements, CTO has been reported in approximately onethird of patients undergoing diagnostic coronary angiography. This thematic issue goes in depth into “coronary CTO ” that still represents the last frontier in percutaneous coronary intervention (PCI). ...
