Key result
Improved retrograde techniques achieve successful recanalization of a CTO after a prior failed attempt.
Why the study?
It has not been fully demonstrated whether different strategies and techniques in the retrograde approach for CTO can improve final procedural success.

Single-case failure of retrograde CTO PCI despite access; leaves open whether advanced strategies improve success rates.
Case Report (n=1)
This case demonstrates that combining improved strategies and techniques can achieve success in CTO PCI via the retrograde approach even after a previous failure.
Matsumi et al. (2008) conducted a case report in Chronic total coronary artery occlusion (CTO) (n=1). Retrograde approach in percutaneous coronary intervention was evaluated on Final procedural success. A combination of improved strategies and techniques for the retrograde approach achieved final success in a chronic total occlusion lesion after an initial failed attempt 3 years prior.
