When and how to perform an antegrade dissection/re-entry approach using the crossboss and stingray catheters

Abstract

Chronic Total Occlusion (CTO) remains the most challenging lesion to treat using Percutaneous Coronary Intervention (PCI). Multiple strategies exist to facilitate lesion crossing and subsequent stenting of the target vessel. The antegrade dissection and re-entry (ADR) technique was developed to provide another option for patients to facilitate a successful CTO PCI procedure. This chapter provides a step-by-step approach to learn the technique.
