Early elastic response after angioplasty is significant when considering the possible development of restenosis. The purpose of this study was to compare early elastic recoil within 10 minutes after successful percutaneous transluminal coronary angioplasty and early lumen loss at 24 hours after angioplasty in a cutting balloon group and a conventional balloon group.Extent of early elastic recoil was quantitatively measured as the difference of mean balloon diameter at maximal inflation pressure and minimal luminal diameter after angioplasty in 82 cutting balloon-treated lesions and 51 conventional balloon-treated lesions.Reference diameter and balloon/artery ratio were similar between the cutting balloon and conventional balloon groups (2.89 0.47 mm vs. 2.88 0.60 mm; 1.19 0.11 vs. 1.19 0.13, respectively). Early elastic recoil after angioplasty was significantly smaller in the cutting balloon than the conventional balloon group (0.96 0.40 mm vs. 1.12 0.37 mm, respectively; p = 0.04). Also, the mean amount of lumen loss from 10 minutes after angioplasty to 24 hours after was significantly smaller in the cutting balloon than the conventional balloon group (0.08 0.28 mm vs. 0.20 0.33 mm, respectively; p = 0.02).There is significantly less early elastic recoil in the cutting balloon angioplasty than in the conventional balloon angioplasty group. The efficacy of cutting balloon continues 24 hours after angioplasty.Read More
