Abstract

Several cases of stent strut fractures (SSFs) have recently been reported following drug-eluting stent (DES) implantation Although SSF is a rare complication, it has been suggested to be a cause of restenosis. To date, a number of cases of stent fracture have been associated with sirolimus-eluting stents and they occurred from 2 days to about 2 years after the initial procedure. We report here on a case of paclitaxel-eluting stent fracture at the time of stent placement in a calcified coronary lesion.

Residual stenosis was seen in the middle of the RCA. (B) IVUS finding at proximal stent edge site. (C) Absence of stent strut in cross-sectional images at the transitional zone between eccentrically calcified lesion and mild atherosclerotic plaque lesion. (D) IVUS finding at the eccentrically calcified site. (E) Longitudinal view.
