OBJECTIVE: The authors aimed to compare the clinical outcomes with repeat drug-eluting stent (DES) implantation utilizing the same type versus an alternate DES type for in-stent restenosis (ISR) of DES.
BACKGROUND: : DES are proven as an effective treatment for bare metal ISR.
METHODS: A cohort of 116 patients previously treated with a sirolimus-eluting stent (SES) or a paclitaxel-eluting stent (PES) who presented with angiographic ISR were treated with repeat DES. Of these, 62 (53.4%) were treated with different DES and 54 (46.6%) were treated with the same DES. This cohort was followed for clinical events at 30 days, 6 months, and 1 year.
RESULTS: Baseline characteristics were similar except for more diabetes among patients receiving the different type of DES. Of the 116, overall 16.4% of the DES were implanted for previous ISR and 2.6% had previously received brachytherapy. At 6 months, the overall target vessel revascularization (TVR) rate was 12.2% for the entire cohort. The TVR-major adverse cardiac event (MACE) rate for the patients treated with different DES was 14.5% and 16.7% for the same DES (P = 0.750). Overall TVR rate at 1 year was 28.8%. The TVR-MACE was 32.6% for different DES and 35.0% for the same DES (P = 0.814).
CONCLUSIONS: Reimplantation of DES for the treatment of DES ISR (same or different) is safe but associated with a high rate of recurrences at 1 year regardless of the initial DES type. Other treatment modalities for ISR of DES should be considered to further improve the overall TVR-MACE.
