Abstract/OtherAbstract:
BACKGROUND: The difference in clinical outcome between paclitaxal-eluting stents (PES) and sirolimus-eluting stents with bio-degradable polymer (SES-BDP) for bifurcation lesions remains unclear. The present study aimed to investigate the one-year clinical outcome after DK crush stenting using PES (Taxus(TM)) vs. SES-BDP (Excel(TM)) from our database.
METHODS: A total of 275 patients (90 from the DKCRUSH-I and 185 from the DKCRUSH-II study) were studied. The primary endpoint was the occurrence of major adverse cardiac events (MACE) at 12 months; including cardiac death, myocardial infarction (MI), or target vessel revascularization (TVR). The rate of binary restenosis and stent thrombosis served as secondary endpoints.
RESULTS: At follow-up, minimal luminal diameter (MLD) in the Taxus group was (2.11 ± 0.66) mm, with resultant increased target lesion revascularization (TLR) 12.2% and TVR 14.4%, significantly different from the Excel group; (2.47 ± 0.56) mm, P < 0.001, 3.2%, P = 0.006, 4.9%, P = 0.019, respectively. As a result there was a significant difference in MACE between the Taxus (20.0%) and Excel (10.3%, P = 0.038) groups. Overall stent thrombosis was monitored in 11 patients (4.0%), with five in the Excel group (2.7%) and six in the Taxus group (6.7%). All stent thrombosis in the Excel group was classified as early, and all were defined as late in the Taxus group.
CONCLUSION: The Excel stent had lower rate of stent thrombosis, TLR, TVR, and composite MACE at 12-month after an indexed stenting procedure, compared to the Taxus stent.
