Stent fracture (SF) and its related restenosis are concerns about sirolimus–eluting stent (SES) implantation. However, the differences in the prevalence of SF and its related restenosis compared with other dug–eluting stent (DES) implantations and the effect of stented vessel were unknown. We assessed SF and restenosis at SF site in terms of stented vessel after DES implantations.
A total of 10367 stent–implanted lesions (SES 5479, everolimus–eluting stent [EES] 2190, paclitaxel–eluting stent [PES] 1204, zotarolimus–eluting stent [ZES] 637, biolimus–eluting stents [BES] 857) from November 2002 to October 2011 were analyzed at midterm follow–up. Stented vessels were classified into two groups: right coronary artery (RCA) and non–RCA.
The table shows data. The prevalence of SF in EES, PES, and ZES was significantly lower than that in SES in both RCA and non–RCA. The prevalence of SF was similar between SES and BES in both RCA and non–RCA. The prevalence of SF with restenosis in the non–RCA was lower than that in the RCA in each DESs except for BES. The prevalence of SF with restenosis in BES was relatively lower in the RCA.
The effects of DES on SF–related restenosis depend on the vessel site. The problems of SF–related restenosis in the RCA still remain unsettled.
