光学相干断层成像技术在经皮冠状动脉血管内冲击波能量钙化碎裂术治疗冠状动脉钙化斑块中应用的研究进展

Research Progress on the Role of Optical Coherence Tomography in Intravascular Lithotripsy During Percutaneous Coronary Intervention for the Treatment of Calcified Coronary Plaques

冠状动脉钙化病变会增加介入手术的难度和并发症发生率,导致患者预后不良,在支架置入前对钙化斑块进行充分预处理将有效减少不良结局发生。经皮冠状动脉血管内冲击波能量钙化碎裂术(IVL)能有效破坏钙化斑块,从而有利于支架输送和促进支架膨胀完全。光学相干断层成像(OCT)可准确识别钙化病变,评估钙化斑块经IVL预处理效果,指导介入手术策略制定。本文将综合近年来此领域研究进展,总结OCT在IVL治疗冠状动脉钙化病变中的作用。

Coronary artery calcification is associated with increased difficulty and complications during interventional procedures,and adequate pretreatment prior to stent placement might be effective in reducing the incidence of adverse outcomes.Intravascular lithotripsy(IVL)is effective in disrupting calcified plaques,facilitating optimal stent delivery and expansion.Optical coherence tomography(OCT)can accurately identify calcified lesions,assess the effect of pretreatment with IVL,and guide the selection of treatment strategies.The aim of this article is to summarize the recent research progresses on the role of OCT in IVL for the treatment of calcified coronary lesions.
