Abstract:
Objective: To investigate the prognostic factor for small side branch (SB) occlusion during coronary bifurcation intervention with the incidence rate of peri-procedural myocardial injury (PMI) in relevant patients.
Methods: A total of 925 consecutive patients who received coronary bifurcation intervention were enrolled and there were 949 SB lesions ≤ 2.0 mm conifrmed by quantitative coronary angiography (QCA). The patients were divided into 2 groups: SB occlusion group,n=85, including 86 bifurcation lesions and Non-SB occlusion group,n=840, including 863 bifurcation lesions. The clinical characteristics, QCA findings and PCI procedural conditions were studied by Multivariate logistic regression analyses to explore the independent predictors of SB occlusion and to compare the incidence rate of PMI.
Results: The total SB occlusion rate was 9.1% (86/949). SB occlusion group had the higher incidence rate of PMI (26/83, 31.3%) vs (77/821, 9.4%) and peri-operative MI mortality(6/83, 7.2%) vs (11/821, 1.3%) than Non-SB occlusion group, both P<0.001. In SB occlusion group, the diameter ratio of main vessel (MV)/SB was obviously higher than Non-SB occlusion group,P<0.001. The independent predictors of SB occlusion included in true bifurcation lesion, irregular plaque, pre-dilation of SB, TIMI lfow grade of pre-procedural SB, stenosis degrees of distal MV and bifurcation core, bifurcation angle, diameter ratio of MV/SB and the stenosis degree of SB before MV stenting.
Conclusion: Coronary bifurcation lesion patients with SB occlusion had the higher risk of PMI during the interventional procedure.
