Antegrade Approach of Percutaneous Coronary Intervention for Chronic Total OcclusionSource of Funding No funding obtained.
Chronic total occlusion (CTO) is a common challenge accounting for 10% of coronary lesions found on coronary angiography. Patients are frequently referred for bypass surgery because percutaneous coronary intervention is challenging in this subset. Recent advances in the hardware as well as the technical expertise and an algorithm approach have improved the success to more than 90%.
Antegrade approach is the cornerstone for managing CTO and has two distinct strategies: antegrade wire escalation, and antegrade dissection and reentry strategy. Step-wise approach to perform these procedures and the use of adjunct imaging are discussed.
