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.
