A complex case of right coronary artery chronic total occlusion treated by a successful multi-step Japanese approach

Percutaneous revascularization of coronary chronic total occlusion remains a challenge for the interventional cardiologist. Operator experience and specific tips and tricks for more difficult cases are needed to obtain procedural success in the majority of situations. We describe a case of successful reopening of a chronically occluded right coronary artery using a retrograde wire as a landmark of the true lumen and a novel penetration device (Tornus, Ashai) to facilitate balloon and stent deployment.
