Why the study?
The impact of modern dissection and reentry techniques on the long-term outcomes of CTO PCI remains controversial.

May warrant preferring IP tracking in CTO PCI when feasible; leaves open whether RCTs will confirm these observational associations.
Does extraplaque tracking compared to intraplaque tracking affect clinical outcomes in patients undergoing chronic total occlusion percutaneous coronary intervention?
Extraplaque tracking in CTO PCI is associated with a higher risk of MACE and TVR at 1 year compared to intraplaque tracking, likely driven by greater baseline lesion complexity.
