Why the study?
Contemporary CTO PCI incorporates wire escalation and dissection/re-entry strategies, but whether the mode of successful recanalisation influences collateral function regression after CTO PCI remains to be identified.

Collateral regression after CTO PCI appears technique-independent; hypothesis-generating and requires prospective validation before guiding strategy.
Does the mode of successful recanalisation influence collateral function regression after CTO PCI?
Collateral flow significantly reduces over time after successful CTO PCI, regardless of the recanalisation technique used.
