Key result
Retrograde epicardial collateral stenting successfully revascularizes a right coronary artery CTO.
Why the study?
Chronic total occlusion occurs in 30-40% of coronary artery disease patients and retrograde revascularization through collateral channels has been previously described but not via epicardial collateral stent passage.
Answers are grounded in this paper and cite their sources.
This case report demonstrates the feasibility of retrograde stent passage through an epicardial collateral for CTO revascularization.
Chronic total occlusion (CTO) may occur in as many as 30-40% of patients with coronary artery disease. Retrograde revascularization through a collateral channel has been described earlier. We report the first case of retrograde passage of a stent through an epicardial collateral to revascularize a right coronary artery CTO.

Bansal et al. (2008) studied this question. Retrograde passage of a stent through an epicardial collateral vessel was successfully performed to revascularize a right coronary artery chronic total occlusion.
