The coronary guidewire re-crossing position before the final kissing balloon post-dilation is important to reduce the incidence of incomplete stent apposition in bifurcation lesions. Angiography and intravascular ultrasonography are unreliable at detecting the site of wire re-crossing. The high resolution of optical coherence tomography (OCT) offers the advantage of precise assessment of construction in bifurcation. However, the OCT technique still has some limitations, including the requirement for additional contrast and expense. We present two cases where the ClearStent Live system technique was used to estimate the wire location, which was verified by using OCT. In conclusion, ClearStent can be used with or to replace the intracoronary imaging technique in selected cases.
最终亲吻球囊后扩张前冠状动脉导丝重新穿过的位置对于降低分叉病变中支架贴壁不全的发生率很重要。血管造影和血管内超声在检测导丝重新穿过的部位时并不可靠。光学相干断层扫描（OCT）的高分辨率为精确评估分叉处结构提供了优势。然而，OCT技术仍有一些局限性，包括需要额外的造影剂和费用较高。我们介绍两例使用ClearStent Live系统技术来估计导丝位置的病例，这一位置通过OCT得以验证。总之，在某些选定的病例中，ClearStent可与冠状动脉内成像技术一起使用或替代该技术。
