Ostial left circumflex lesion with calcified nodule successfully treated with excimer laser coronary atherectomy and drug-coated balloon.

ABSTRACT: Stenting for severely calcified lesions has a higher risk of stent restenosis or stent failure than stenting for lesions without calcification, and stenting for complex lesions including ostial or bifurcation lesions sometimes causes plaque shift which leads to side branch occlusion. A calcified nodule (CN) is considered one of the culprits for stable angina or acute coronary syndrome. However, the optimal strategy for this lesion is not well clarified. We report a patient who presented stable angina with a CN at the ostial left circumflex artery. In this case, pretreatment with excimer laser coronary atherectomy (ELCA) and scoring balloon dilatation followed by drug-coated balloon (DCB) dilatation successfully prevented plaque shift caused by stenting in the acute phase. In addition, it a
