目的：本研究的目的是评估通过频域光学相干断层扫描（FD-OCT）进行无保护非开口左主干（LM）成像的可行性。方法和结果：我们对用于成像位于非开口处的病变的OCT研究进行了回顾性分析LM。对OCT研究进行分析，以检测不同LM/分叉段中的伪影帧数。OCT横截面图像用于评估面积测量。OCT纵向重建用于获得LM长度。标准定量冠状动脉造影（QCA）被用作参考方法。共有54例非开口部LM疾病患者入组研究。LM伪影帧的平均数量为8 +/- 10，相当于分析的LM帧总数的19%。伪影帧的百分比根据分析的节段而显著不同：LM近端43.3%，LM中段11.4%，LM远端2.1%，左前降支开口1.9%，左旋支开口0%（p
Aims: The aim of this study was to assess the feasibility of unprotected non-ostial left main (LM) imaging by frequency domain optical coherence tomography (FD-OCT).Methods and results: We conducted a retrospective analysis of OCT studies performed to image lesions located in the non-ostial LM. OCT studies were analysed to detect the number of artefact frames in the different LM/bifurcation segments. OCT cross-sectional images were used to assess area measures. OCT longitudinal reconstructions were used to obtain the LM length. Standard quantitative coronary angiography (QCA) was used as the reference methodology. A total of 54 patients with non-ostial LM disease entered the study. The mean number of LM artefact frames was 8 +/- 10, corresponding to 19% of the total number of LM frames analysed. The percentages of artefact frames differed significantly according to the segment analysed: 43.3% proximal LM, 11.4% mid LM and 2.1% distal LM, 1.9% ostial left anterior descending artery and 0% ostial left circumflex artery (p
