Impact of Bifurcation Angle on Side Branch Occlusion During Coronary Bifurcation Intervention in Relevant Patients / 中国循环杂志

ABSTRACT

Objective:To investigate the impact of bifurcation angle (BA) on side branch occlusion (SBO) during percutaneous coronary intervention (PCI) in relevant patients. Methods: A total of 1171 consecutive patients with 1200 bifurcation lesions who received one stent technique were studied. Based on the median BA of 52°, the patients were divided into 2 groupsLow angle group, n=587 patients with 600 bifurcation lesions and High angle group, n=584 patients with 600 bifurcation lesions. SBO was deifned by either side branch blood lfow disappeared or TIMI grade decreased after PCI. The occurrence rate of SBO was investigated and the impact of BA on SBO during PCI was evaluated by multivariate Logistic regression analysis. Results:SBO occurred in 88/1200 (7.33%) bifurcation lesions. The occurrence rate of SBO in High angle group was igher than Low angle group (10.5%vs 4.2%, P Conclusion:High BA was an independent predictor of SBO after the main vessel stent implantation, which should not be ignored in clinical practice.
