摘　　要：冠状动脉严重钙化病变介入手术风险高、操作难度大,向来是令心脏介入医师感到棘手的难题。以腔内影像学为指导、冠状动脉斑块旋磨术为保障的治疗策略虽被共识所推荐,但在我国的应用比例仍然较低。本中心在旋磨术处理严重钙化病变方面积累了较多经验,尤其在左主干病变、开口病变以及迂曲成角病变等复杂场景下的应用。本文报道1例位于右冠状动脉开口的巨大钙化斑块致偏心性严重狭窄病变的介入治疗,讨论血管内超声指导旋磨术进行斑块修饰及部分消蚀的方法及策略。Coronary artery heavy calcif ication is always challenging scenarios for interventional cardiologists.Although the treatment strategy guided by intravascular imaging and guaranteed by rotational atherectomy(RA)is recommended by consensus,the application rate of RA in my country is still relatively low.Our center has accumulated a lot of experience in the use of rotational atherectomy to treat severe calcified lesions,especially in complex scenarios such as left main trunk lesions,ostial lesions,and severe vessel tortuosity.Here is a case of interventional treatment of severe eccentric stenosis caused by a huge calcified plaque at the right coronary artery ostium.The method and strategy of plaque modif ication and partial ablation by intravascular ultrasound-guided RA are discussed.
