Key result
Dual-lumen microcatheter successfully recanalizes CTO after single-lumen failure.
Why the study?
Recanalization of a CTO is complex, and most PCI CTO failures stem from the inability of the wire to pass through the occlusion.
Does a dual-lumen catheter enable successful guidewire crossing in CTO PCI after single-lumen microcatheter failure?

Does a dual-lumen catheter enable successful guidewire crossing in CTO PCI after single-lumen microcatheter failure?
Answers are grounded in this paper and cite their sources.
A dual-lumen catheter can provide the necessary support for successful guidewire crossing in CTO PCI when a single-lumen microcatheter fails.
Recanalization of a chronically occluded coronary artery (CTO) is one of the most complex percutaneous coronary interventions (PCI) in the field of interventional cardiology. In addition to all available recanalization techniques, most PCI CTO failures go to the inability of the wire to pass through the occlusion. We report a CTO case successfully treated using a dual-lumen catheter after single-lumen microcatheter (MC) failure (not enough support for the guidewire to cross the occlusion).

Juričić et al. (2020) conducted a case report in Chronic Total Occlusion (CTO) (n=1). Dual-lumen microcatheter (Sasuke) vs. Single-lumen microcatheter (Finecross) was evaluated on Successful recanalization of chronic total occlusion. Dual-lumen microcatheter was successfully used to treat a chronic total occlusion after single-lumen microcatheter failure.
