This case report demonstrates a unique strategy requiring a 2.5 mm burr to treat in-stent restenosis of an originally underexpanded stent, implanted in a heavily calcified lesion within a giant aneurysm by Kawasaki disease. Despite our procedural success, it should be emphasized that stent implantation in undilatable lesions should be avoided. When an angiographically calcified lesion within an ectatic segment is observed in a patient with Kawasaki disease, it is recommended that the operator evaluates in detail the severity and location of calcification using intravascular ultrasound imaging and pays meticulous attention to lesion preparation.
