title: Usefulness of the Corsair microcatheter for treatment of complex chronic total occlusion.
abstract: Percutaneous coronary intervention (PCI) for the treatment of chronic total occlusion (CTO) is one of the most technically challenging areas of interventional cardiology. When CTO is combined with angulation and tortuosity of the coronary artery, the technical complexity of PCI for CTO is magnified. In this report, we describe a case of successful revascularization of a CTO lesion in the complex circumflex anatomy using a novel microcatheter (the Corsair catheter) along with an antegrade approach to facilitate guidewire passage through a proximal steep angulation and to cross the circumflex CTO lesion that was unresponsive with conventional microcatheters.
