Stent systems
Overall 85 (1.7 per patient) implanted stents; STENTYS® (paclitaxel), STENTYS-SES® (sirolimus), Xposition S® (sirolimus) Diameter range 2.5–4.5 mm Length 17–37 mm
Overall 96 (1.8 per patient) implanted stents; XIENCE®, promus element®, resolute integrety®, resolute Onyx®, Osiro®, BioMatrix® Diameter range 2.25–5.0 mm Length 8–32 mm
Values are number (n)standard deviation (SD), number (%) or meanstandard deviation. A value <0.05 is considered significant. SExS = self-expanding drug eluting stent; BExS = balloon expanding drug eluting stent; DES = drug eluting stent; EPD = embolic protection device; SVG = saphenous vein graft; TIMI = thrombolysis in myocardial infarction.
