Side branch preservation using tip detection-antegrade dissection re-entry after failed subintimal tracking and re-entry in chronic total occlusion: a case report.

ABSTRACT:

Background

Techniques for treating difficult chronic total occlusions (CTOs) have evolved with the discovery of the tip detection-antegrade dissection re-entry (TDADR) guided by intravascular ultrasound (IVUS). This case demonstrates TDADR as a viable bailout in failed subintimal tracking and re-entry (STAR) technique.

Case summary

A 78-year-old man with stable angina on optimal medical therapy had exertional angina pectoris secondary to a residual CTO lesion of the left circumflex coronary (LCX) artery. Percutaneous coronary intervention was performed for a mid-LCX CTO with a blunt proximal stump where the dissection plane expanded along the main vessel and side branch 2. Due to lack of promising collaterals for the retrograde approach, STAR successfully recanalized side br
