Abstract

Objectives: To report 1- and 2-year clinical outcomes of patients receiving platinum chromium everolimus-eluting stents (PtCr-EES) in the prospective, single-arm PLATINUM small vessel (SV) and long lesion (LL) studies. Background: Small vessel diameter and long lesion length are independently associated with increased risk of adverse cardiac events after drug-eluting stent implantation. Methods: The PLATINUM SV study enrolled 94 patients with coronary artery lesions in vessels ≤2.25 mm to <2.50 mm in diameter and & ≤28 mm in length. The PLATINUM LL study enrolled 102 patients with lesions >24 to & ≤34 mm long in vessels ≤2.50 to & ≤4.25 mm in diameter. The primary endpoint for both studies was target lesion failure (TLF) at 1 year compared to a prespecified performance goal based on outcomes with the TAXUS Express paclitaxel-eluting stent in small vessels and long lesions. Results: One-year TLF rates with the PtCr-EES were significantly (P < 0.001) lower than the predetermined performance goals: 2.4% versus 21.1% in the SV cohort and 3.2% versus 19.4% in the LL cohort. Cumulative rates of TLF to 2 years were 4.7% in the SV cohort and 8.8% in the LL cohort. No myocardial infarction or ARC definite/probable stent thromboses occurred in either cohort through 2-year follow-up. Conclusions: The clinical efficacy and safety outcomes observed in these small vessel and long lesion cohorts support the use of the PtCr-EES in the treatment of small diameter vessels and long lesions.
