A Case of a Zotarolimus-Eluting Stent Fracture in the Left Anterior Descending Artery in a Patient Undergoing Hemodialysis

  • 1Department of Internal Medicine, Korea University Ansan Hospital, Ansan, Korea.


Although stent fracture after implantation of a drug-eluting stent (DES) is a rare complication, it has been suggested to be a cause of restenosis. To date, most DES fractures have been associated with sirolimus-eluting stents. We describe here a case of a zotarolimus-eluting stent fracture after 8 months of stent placement in a calcified left anterior descending artery lesion in a patient undergoing hemodialysis.

  • FIG. 1 Initial coronary angiography showed diffuse stenosis in the proximal and mid portions of the LAD. LAD: left anterior descending artery.

  • FIG. 2 Post-PCI angiography revealed well-deployed ZES. PCI: percutaneous coronary intervention, ZES: zotarolimus-eluting stent.

  • FIG. 3 Follow-up coronary angiography and fluoroscopy showed a gap in the stent strut. A-D: a gap in the stent strut.

  • FIG. 4 IVUS showed absent stent strut at the fractured site. Serial IVUS findings at the fractured site. IVUS: intravascular ultrasonography, white arrow: fractured site.
