Percutaneous coronary intervention (PCI) was performed for chronic total occlusion of the proximal right coronary artery in a 70-year-old male with unstable angina. The forceful manipulation of the guide catheter led to an aortocoronary dissection involving the right Valsalva sinus and the ascending aorta. Intracoronary ultrasound (ICUS) showed the important characteristics of the dissection, enabling successful coronary stenting under ICUS guidance.
对一名患有不稳定型心绞痛的70岁男性，针对其右冠状动脉近端慢性完全闭塞病变进行了经皮冠状动脉介入治疗（PCI）。导引导管的强力操作导致了主动脉冠状动脉夹层，累及右冠窦和升主动脉。冠状动脉内超声（ICUS）显示了夹层的重要特征，使得能够在ICUS引导下成功进行冠状动脉支架置入术。
