title: Successful percutaneous coronary intervention of chronic total occlusion of the right coronary artery using "bidirectional kissing-balloon" technique.
abstract: We report on a 74-year-old man with chronic total occlusion (CTO) of the right coronary artery treated with percutaneous coronary intervention using the bidirectional kissing-balloon technique. When an antegrade approach fails, a retrograde approach to recanalize a CTO is reasonable. However, when the exit of the CTO is bifurcated and a protection wire does not advance antegrade into the side branch after wire externalization, loss of blood flow after ballooning or stenting may result. We report on the usefulness of the bidirectional kissing-balloon technique for a retrograde approach to chronically totally occluded coronary arterial bifurcation lesions.
