Fracture of a sirolimus-eluting stent with migration.

In this case report, we describe a rare patient who experienced complete fracture of a sirolimus-eluting stent that was implanted for a focally calcified lesion of the right coronary artery ostium. Although the fractured fragment migrated somewhere in the systemic circulation, fortunately there were no complications. Implantation for ostial lesions of the right coronary artery should be performed with great care.
