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

Abstract

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.

Incidence and clinical impact of fracture of drug-eluting stents widely used in current clinical practice: Comparison with initial platform of sirolimus-eluting stent

“…They reported that stents with modular structure demonstrated better behavior than slotted tube ones in the tensile-compression fatigue test, and stents made of cobalt alloy had a longer endurance due to its better mechanical properties than stainless steel. In addition, clinical reporting of EN stent fracture is rare; to the best of our knowledge, it has been reported in only 3 cases [7][8][9]. These lines of available evidence strongly support the results of our study.…”
