Refractory In-Stent Restenosis Attributable to Eruptive Calcified Nodule

A 75-year-old female patient on hemodialysis presented with non–ST-segment elevation myocardial infarction. After successful primary percutaneous coronary intervention, in-stent restenosis (ISR) occurred 3 consecutive times. Intravascular imaging assessment during the repeated percutaneous coronary...

Summary:A 75-year-old female patient on hemodialysis presented with non–ST-segment elevation myocardial infarction. After successful primary percutaneous coronary intervention, in-stent restenosis (ISR) occurred 3 consecutive times. Intravascular imaging assessment during the repeated percutaneous coronary intervention indicated that the ISR was not associated with neointimal hyperplasia but was mainly attributed to a calcified nodule, which protruded into the lumen. We applied excimer laser catheter ablation to avoid another ISR. (Level of Difficulty: Intermediate.) [Display omitted]
