  • Beschreibung: <jats:p> A 62-year-old man with effort angina underwent percutaneous coronary intervention in our hospital. The target lesion was severely calcified at the mid part of the right coronary artery. Pre-procedural intravascular imaging and optical frequency domain imaging showed a calcified nodule at the lesion. We performed rotational atherectomy with a 2.0 mm burr and observed an increase in the lumen area; however, a large amount of calcified nodule persisted. We decided to perform rotational atherectomy with a burr size of 2.25 mm; however, distal embolization of the calcified nodule occurred. We failed to retrieve the embolus; hence, we performed balloon dilatation with a 2.0-mm balloon, which was successfully performed. Yet, the lesion with the embolus immediately recoiled. Finally, a drug-eluting stent was implanted in both the distal lesion with the embolus and the lesion with the calcified nodule. Final coronary angiography showed good results. We confirmed good stent expansion and that calcified nodule was compressed outside the stent. Atherectomy of a calcified nodule is effective at achieving sufficient stent expansion and reducing the risk of vessel perforation. However, we experienced distal embolization of the calcified nodule at the time of rotational atherectomy and so distal embolization should be considered at the time of treatment of calcified nodule. </jats:p>
