A 46-year-old man was admitted with electrocardiographic abnormality (Q-wave in V1 to V4 and T-wave inversion in V1 to V5). Echocardiography showed left ventricular systolic dysfunction (ejection fraction: 41%) with akinetic motions of anterior and anteroseptal wall, which corresponded to myocardial infarction of left anterior descending artery (LAD) territory. Computed tomography angiography showed noncalcified stenosis at proximal LAD (A). Conventional coronary angiography, performed 4 days later, showed a braid-like appearance with significant stenosis and aneurysmal dilation at the proximal LAD (B). Intravascular ultrasound revealed that this segment was composed of multiple echoic channels resembling a lotus root (thick divisions surrounded by the external elastic membrane) (C, Online Video 1), suggesting spontaneous recanalization of the thrombotic occlusion due to Kawasaki disease (1). We performed intravascular ultrasound-guided percutaneous coronary intervention with a 4.0 × 18 mm–sized everolimus-eluting stent. The patient was discharged and is doing well without adverse cardiovascular events.
