The Application of Dual-wire Balloon in The Treatment of Coronary Bifurcation Lesions

Objectives To assess the efficiency and safety of dual-wire balloon angioplasty side branch combined stenting the main branch in the treatment of coronary bifurcation lesions. Methods This study included thirty-six patients with 41 coronary bifurcation lesions. Selective dual-wire balloon angioplasty was performed in side branch and/or in main branch, and implantation of stents was performed in main branch only. Clinical outcome and major adverse cardiac events were observed in-hospital and follow-up. Results Success rate of side branch dilatation before main branch stenting was 100%; main branch direct stenting performed in 4 cases; success main branch dilatation performed in the other 37 cases; kissing technique was performed successfully in 5 cases, which side branch was jailed after main branch stenting with TIMI grade 0-2 flow. No Q-wave myocardial infarction, acute revascularization and death occurred during in-hospital. Clinical follow-up was available in all patients. No Q-wave myocardial infarction, revascularization and death occurred, angina pectoris recurred in three patients, released by strengthen drug treatment. Conclusions Dual-wire balloon angioplasty side branch combined stenting the main branch is simple, safe and effective for the treatment of coronary bifurcation lesions.
