Abstract

Objective: This study aimed to validate the effectiveness, accuracy, and feasibility of the cut-plane method for measuring the side branch (SB) ostium area in three-dimensional optical coherence tomography (3D-OCT) pullbacks performed in the main branch (MB).

Methods: A total of 109 sets of OCT pullbacks from the MB and SB of coronary artery bifurcation lesions were analyzed using Vivolight OCT software. Measurements of the SB ostium area from the MB and SB pullbacks were analyzed. Measurements of the SB ostium area from the actual SB pullback were used as a reference. 3D cut-plane analysis was used to estimate the correlations and mean errors with the reference measurements.

Results: Thirty-four sets of OCT images from the C7XR system and 75 sets from the Cornaris^TM system were analyzed using Vivolight software. There was a strong correlation between the reference measurements of the SB ostium area and the measurements obtained through 3D cut-plane analysis in the overall dataset (r = 0.925). This correlation was observed consistently with both the C7XR system (r = 0.955) and Cornaris^TM system (r = 0.900). Similar results were found in subset analyses of true and nontrue bifurcations (r = 0.936; r = 0.898, respectively) and in left main (LM) or non-LM bifurcation subsets (r = 0.932; r = 0.873, respectively).

Conclusions: There were strong correlations between measurements of the SB ostium area by 3D-OCT and the reference measurements, and thus may be a reliable and accurate alternative to direct OCT pullback examinations of the SB.

验证用于精确测量冠状动脉分叉病变侧支骨膜面积的切平面法：3D-OCT 分析

研究目的本研究旨在验证切面法测量主支（MB）三维光学相干断层扫描（3D-OCT）拉回图中侧支（SB）骨膜面积的有效性、准确性和可行性：方法：使用 Vivolight OCT 软件分析了冠状动脉分叉病变的主支和侧支的共 109 组 OCT 拉片。分析了从 MB 和 SB 拉回的 SB 骨膜面积的测量结果。以实际 SB 拉回的 SB 管腔面积测量值作为参考。三维切面分析用于估算与参考测量值的相关性和平均误差：使用 Vivolight 软件分析了来自 C7XR 系统的 34 组 OCT 图像和来自 CornarisTM 系统的 75 组图像。在整个数据集中，SB 骨桥区的参考测量值与通过三维切面分析获得的测量值之间存在很强的相关性（r = 0.925）。这种相关性在 C7XR 系统（r = 0.955）和 CornarisTM 系统（r = 0.900）中都得到了一致的观察。在真实和非真实分叉子集分析（r = 0.936；r = 0.898，分别为 0.936 和 0.898）以及左主干（LM）或非 LM 分叉子集分析（r = 0.932；r = 0.873，分别为 0.932 和 0.873）中也发现了类似的结果：结论：3D-OCT 对 SB 管腔面积的测量结果与参考测量结果之间存在很强的相关性，因此可以作为 SB 直接 OCT 回抽检查的可靠而准确的替代方法。
