Rotational atherectomy with/without low-pressure balloon dilation has been a mainstay of interventional treatment for stenosis due to the coronary sequelae of Kawasaki disease (KD). Here, we report a restenosis case of probable coronary sequelae of KD treated with rotational atherectomy with low-pressure 2.5-mm balloon dilation 6 months previously. Under the guidance of optical frequency domain imaging, we performed rotational atherectomy followed by 2.5-mm drug-coated balloon (DCB) dilation for an atherosclerotic restenosis at the inlet of a calcified aneurysm in the proximal left anterior descending coronary artery. Coronary angiography 6 months later showed no apparent progression of vessel narrowing, and we could defer repeat intervention. The present case suggests that rotational atherectomy followed by DCB dilation could be an alternative revascularization therapy of choice in coronary KD sequelae complicated with atherosclerosis.
