With great interest I read the report by Weissman et al. (1) regarding intravascular ultrasound (IVUS) analysis of polymer-based paclitaxel-eluting stents. The investigators stated in the text that "positive remodeling assessed as the absolute increase in the external elastic membrane volume over time tended to be slightly more prominent with the TAXUS stent (7.66 ± 48.64 mm3 vs. –12.29 ± 36.05 mm3, respectively, p = 0.064)." Also Figure 1 suggested positive remodeling in the TAXUS stent. However, Table 2 of their article (1) shows an inconsistent result, that is, decrease of external elastic membrane volume in the TAXUS-stent group (283 ± 91 mm3 at postimplantation vs. 280 ± 89 mm3 at nine-month follow-up). Because a previous IVUS analysis has also suggested positive remodeling in the TAXUS stent (2), it may be of great importance to better clarify this result.
