Does the end justify the means? The contemporary role of dissection/re‐entry strategies for recanalization of coronary chronic total occlusions

Abstract

Antegrade and retrograde dissection/re-entry techniques are frequently utilized in contemporary CTO PCI, especially for complex lesions. One-year outcomes with modern dissection/re-entry techniques appear favorable and comparable with those achieved after intraplaque crossing, supporting their increased use. Randomized data on the procedural safety, efficiency, and long-term outcomes of subadventitial CTO PCI techniques are needed.
