Key result
Novel reverse wire trapping facilitates antegrade wire crossing in unapproachable CTO lesions.
Why the study?
Percutaneous coronary intervention of chronic total occlusion remains technically challenging, and novel retrograde techniques may improve success rates.
Case Report
The "reverse wire trapping" technique offers a novel solution for creating an antegrade wire route during retrograde CTO PCI when standard methods fail.
Percutaneous coronary intervention (PCI) of a chronic total occlusion (CTO) remains a technical challenge for the interventional cardiologists. Recently, modified techniques based on the retrograde approach have demonstrated that this approach could increase the success rate for PCI of CTO. In the current report, we describe a novel "reverse wire trapping" technique that can help create an antegrade wire route to open CTO after the wire has passed through the CTO retrogradely, even though the retrograde balloon dilatation or antegrade wiring was unapproachable.

Ge et al. (2009) conducted a case report in Chronic total coronary artery occlusion (CTO). Reverse wire trapping technique was evaluated. The novel 'reverse wire trapping' technique facilitated the creation of an antegrade wire route to open chronic total occlusions when retrograde balloon dilatation or antegrade wiring was unapproachable.
