Key result
Retrograde approach via collateral channels improves procedural success rates in CTO PCI.
Why the study?
Many interventionists are held back from using the retrograde approach in CTO PCI due to lack of proper equipment and expertise despite its potential to improve success rates.

Supports retrograde CTO PCI in selected cases; leaves open randomized trials to confirm safety and outcomes.
Provides a detailed guide on techniques and case selection for the retrograde approach in CTO PCI to improve success rates.
Wu et al. (2008) conducted a review in Chronic total occlusion (CTO). Retrograde approach via collateral channels in coronary angioplasty was evaluated. The retrograde approach via collateral channels in coronary angioplasty for chronic total occlusion can improve success rates, with specific techniques detailed for traversing and crossing the CTO.
