We compared the outcome of the self‐expanding Radius stent and the balloon‐expandable Multilink stent serially by angiography and intravascular ultrasound. Successful stent deployment was achieved in 66 lesions of 56 stable angina patients (34 lesions with Radius stents and 32 lesions with Multilink stents). At follow‐up, there were no significant differences in minimal lumen diameter or percent diameter stenosis between the groups, nor in restenosis rates, although the Radius stent group rate was slightly lower (23.5% vs. 31.3%). In the Radius stent group, stent cross‐sectional area (CSA) increased gradually after implantation until the 6‐month follow‐up (8.37 ± 1.83 to 10.16 ± 2.59 mm 2 ; n = 15), giving a larger CSA ( P = 0.03) than the Multilink stent group, which decreased (9.00 ± 2.05 to 8.27 ± 2.15 mm 2 ; n = 17). The lumen CSA was also slightly larger (6.82 ± 3.06 vs. 5.84 ± 1.85 mm 2 ; P = 0.29) in the Radius stent group. These findings indicated that the Radius stent enlarged progressively after implantation, which might be useful for prevention of restenosis.
