Bifurcation lesions represent one of the most challenging lesion subsets in interventional cardiology. The European Bifurcation Club (EBC) is an academic consortium whose goal has been to assess and recommend the appropriate strategies to manage bifurcation lesions. The quantitative coronary angiography (QCA) methods for the evaluation of bifurcation lesions have been subject to extensive research. Single-vessel QCA has been shown to be inaccurate for the assessment of bifurcation lesion dimensions. For this reason, dedicated bifurcation software has been developed and validated. These software packages apply the principles of fractal geometry to address the "step-down" in the bifurcation and to estimate vessel diameter accurately. This consensus update provides recommendations on the QCA analysis and reporting of bifurcation lesions based on the most recent scientific evidence from in vitro and in vivo studies and delineates future advances in the field of QCA dedicated bifurcation analysis.
分叉病变是介入心脏病学中最具挑战性的病变类型之一。欧洲分叉俱乐部（EBC）是一个学术联盟，其目标是评估和推荐处理分叉病变的合适策略。分叉病变的定量冠状动脉造影（QCA）方法已经进行了广泛的研究。单血管 QCA 已被证明对评估分叉病变的尺寸不准确。为此，已经开发和验证了专门的分叉软件。这些软件包应用分形几何的原理来解决分叉处的“阶梯式下降”问题，并准确估计血管直径。本共识更新基于来自体外和体内研究的最新科学证据，就 QCA 分析和报告分叉病变提出了建议，并描绘了 QCA 专用分叉分析领域的未来进展。
