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.
慢性完全闭塞仍然是介入心脏病专家面临的技术挑战。这类病变的成功率较低，仍然是进行血管旁路移植术的重要原因。最近，当先前的正向尝试失败时，经心外膜和间隔穿孔逆行经皮冠状动脉介入治疗完全闭塞被引入作为一种替代方法。我们描述了一个独特的病例，在没有右冠状动脉口的情况下，逆行方法被用作初始再通技术。
