title: Total aorto-ostial chronic occlusion of the right coronary artery successfully recanalized via retrograde approach.
abstract: Chronic total occlusions remain a technical challenge for interventional cardiologists. This group of lesions carries a decreased rate of success and continues to be an important reason for surgical revascularization. Recently, retrograde percutaneous coronary intervention of total occlusions via epicardial and septal perforators was introduced as an alternative approach when a previous antegrade attempt has failed. We describe a unique case where retrograde approach was used as the initial recanalization technique in the absence of a right coronary ostium.
