Figure 1 Change of tissue volume in the plaque prolapse sites within various stent types. The volume of tissue within stent at follow-up (FU) increased as compared with that at post-intervention (PO) in both bare-metal stents (BMS) and paclitaxel-eluting stents (PES), but there was tendency to decrease in sirolimus-eluting stents (SES) (A). The delta volume of tissue within the stent in BMS or PES was significantly larger than that in SES (B). *p < 0.05. Black bars = PO; hatched bars = FU.

Figure 2 Change of the mean area of tissue between plaque prolapse (PP) sites and non-PP sites. In both BMS and PES, the mean area of tissue through the stent struts in both non-PP and PP sites significantly increased at follow-up (A and C). In SES, the mean area of tissue through the stent struts increased in non-PP sites, but decreased in PP sites (B). *p < 0.05. Black bars = PO; hatched bars = FU. Abbreviations as in Figure 1.
