AIMS: To report the four-month and nine-month angiographic results as well as one-year clinical follow-up from the first-in-man study with the silicon carbide and sirolimus-eluting bioabsorbable polymer (poly-L-lactic acid (PLLA) polymer) -coated cobalt-chromium Orsiro stent.
CONCLUSIONS: The Orsiro drug-eluting stent demonstrated potency with low rates of in-stent neointimal hyperplasia and cardiovascular events but warrants further evaluation in a larger population cohort with longer follow-up time points.
METHODS AND RESULTS: A group of 30 patients with documented myocardial ischaemia related to a single de novo coronary stenosis up to 22 mm in length, in vessels with a 2.5 to 3.5 mm reference diameter, and between >50% and <90% diameter stenosis were enrolled at two sites. The primary endpoint of the study was in-stent late lumen loss at nine months. The secondary endpoints included major adverse cardiac events (MACE) at one year defined as the composite of cardiac death, ischaemia-driven target lesion revascularisation (TLR) and target vessel myocardial infarction (MI). Procedural success was 100%. Angiographic late lumen loss was 0.12+/-0.19 mm and 0.05+/-0.22 mm at four and nine months respectively. At one-year clinical follow-up, the composite MACE was 10% with one patient who died from cardiac death and two patients who had ischaemia-driven target lesion revascularisation. There was no report of MI or stent thrombosis.
