Abstract: Coronary artery heavy calcification 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 modification and partial ablation by intravascular ultrasound-guided RA are discussed.
