In the April 2005 issue of Arteriosclerosis, Thrombosis, and Vascular Biology, in the article by Wessely et al (Arterioscler Thromb Vasc Biol. 2005:25:748–753.), the dosage unit on the stent was incorrectly given in mg (page 750, Results, first paragraph). The correct unit is μg, and the complete corrected paragraph is shown below.
“To determine the drug amount on the stent after a single or dual rapamycin coating process, microporous stents were appropriately coated (n=3 each group), and rapamycin concentrations on the stents were determined by HPLC analysis. The drug amount on the stent yielded by single coating was 195±33 μg/cm2 stent surface and 317±45 μg/cm2 by double coating, respectively. The surface of an uncoated and a rapamycin-coated microporous stent is illustrated in Figure 2.”
