TCTAP A-059 Intrahospital and Long-term Outcomes After True Bifurcation Stenting

Abstract

Background: Bifurcation percutaneous coronary intervention (PCI) is challenging and is associated with lower rate of procedural success and higher risk of complications. The aim of this study was to evaluate intrahospital and long-term outcomes of patients who underwent PCI for bifurcation lesions involving main vessel and side branch (SB) with a diameter more or equal 2.5 mm. Method(s): A retrospective analysis of the ongoing Coronary Bifurcation Treatment registry in Latvia Centre of Cardiology. The study population was divided into two groups: provisional single-stenting and systematic double-stenting. Result(s): Totally were screened 4138 PCI procedures performed in Latvia Center of Cardiology in year 2017. Patients with ST elevation myocardial infarction (MI) in last 24 hours were excluded. A total of 133 patients with true non-left main bifurcations were included in this study. 117 patients were treated using provisional technique and 16 with 2-stent technique. Procedural complications were SB occlusion (provisional group 3.4% (n = 4) vs. 2 stent group 0% (n = 0), p = 0.455). Intrahospital complication was periprocedural MI (provisional group 6.8 % (n = 8) vs. 2 stent group 0% (n = 0), p = 0.604). All cases were non-Q MI. 1-year follow-up till 08.2018. was possible in 75 patients (1 stent- 67 patients, 2 stent- 8 patients). Long term complications were death (provisional group 1.5% vs. 2 stent group 12.5%, p = 0.07), target lesion revascularization (TLR) (provisional group 1.5% vs. 2 stent group 0%, p = 0.728). No cases of definite stent thrombosis were observed in both groups. [Figure presented] Conclusion(s): Procedural, intrahospital and long-term complication rate in the treatment of true coronary bifurcation lesions was low and there were no significant differences between groups. There were no proven cases of definite stent thrombosis.Copyright © 2019
