Retrograde CTO PCI-the final frontier-challenges and outcomes

Keypoints Increasing operator experience and an algorithmic approach of transitioning to retrograde approach when antegrade technique fails, have improved the success rates in CTO PCI. Upfront (Primary)retrograde approach is used in some cases with moderate success and the presence of usable collateral is the most important predictor of this. While pursuing improved revascularization rates of CTO PCI, one should also keep in mind patient safety and complications rates.
