Abstract: Objective: To evaluate the safety and efifcacy of cutting balloon combining main branch single stent cross-over technique for treating the patients with coronary bifurcation lesions. Methods: A total of 113 patients with 121 bifurcation lesions treated in our hospital from 2012-01 to 2014-01 were enrolled. Cutting balloon pre-dilation was applied in both main and side branches followed by drug-eluting stent implantation at main branch. The procedural success rates, side branch blood lfow status and complications were observed. Follow-up studied for MACE occurrence was conducted at 9 months after the operation. Results: Quantitative coronary angiography (QCA) presented that the minimum lumen diameters at pre- and post-operation in main branches were (2.12 ± 1.07) mm and (3.24 ± 0.87) mm, in side branches were (1.44 ± 0.73) mm and (1.82 ± 0.64) mm respectively,P<0.05-0.01, the procedural success rate was 100%. There were 11 (9.1%) lesions with dissection at proximal side branch, 5 (4.1%) lesions with side branch TIMI blood lfow
