Abstract：Objective To assess the effect of dual-wire focused force balloon predilation followed by drugeluting stent placement for lesions of small coronary arteries.Methods Through coronary angiography,300 consecutive patients with unstable angina(reference vessel ≤2.75 mm in diameter) were randomly assigned to experimental group(dual-wire focused force balloon predilation group) and control group(balloon predilation group).Restenosis at 9-12 month were followed up through angiography.Clinic improvement and major adverse cardiac event(MACE) at 1 year were assessed.Results Procedural success was achieved in 98.7％(148/150) of patients assigned to experimental group and in 94.7％(142/150) of patients assigned to control group(P ＜ 0.05).Vessels complications in these two groups were 1.3％(2/150) and 5.3％(8/150) respectively(P ＜ 0.05).Less patients in experimental group experienced major adverse cardiac event [ 5/148(3.4％) vs 10/142(7.0％),P ＞ 0.05 ].There was no statistical difference between these two groups regarding restenosis and MACE,but the procedural suecess rate and vessel complications were different.Conclusion Dual-wire focused force balloon predilation reduced the incidence of perioperatine complications and provided tendency of improving outcomes followed by drug-eluting stent placement in small vessels.
