Title: THE COMPARSION OF CUTTING BALLOON ANGIOGRAPHY AND CONVENTIONAL TRANSLUMINAL CORONARY ANGIOPLASTY IN TREATMENT OF IN-STENT RESTENOSIS
Abstract: Objective To determine if the cutting balloon angioplasty has advantages over conventional balloon percutaneous transluminal coronary angioplasty (PTCA) in treatment of in-stent restenosis (ISR). Methods A total of 266 lesions treated for ISR were divided into two groups according to the treatment strategy: conventional balloon PTCA and cutting balloon angioplasty. Angiogram obtained during the procedure and 6 month after the two interventions, and quantitative angiograpic analysis was performed. Results ①Immediately after intervention, the maxium luminal diameter(MLD) in cutting balloon angioplasty group was similar to the one achieved of conventional balloon angioplasty[(2.51±0.65) vs (2.53±0.65) mm, P0.05]. ②At six-month follow-up, the MLD has no significant change between the conventional balloon PTCA group and the cutting balloon angioplasty group [(1.75±0.83) vs (1.96±0.74) mm, P0.05]. ③The cutting balloon angioplasty group has a lower late lumen loss(P0.05). Conclusion We conclude that cutting balloon angioplasty did not increase the MLD immediately after intervention and at 6-month follow-up as compared with conventional balloon angioplasty in the treatment of in-stent restenosis, but with a less late lumen loss.
