Managing calcified nodules remains a clinical challenge.
A 77-year-old man underwent coronary angiography during pre-transcatheter aortic valve implantation workout, showing a severe middle right coronary artery stenosis associated with a suspicious angiographic calcified nodule. Excimer laser was used for plaque preparation and for facilitating subsequent optical coherence tomography intracoronary imaging-guided percutaneous coronary intervention (PCI). Excimer laser coronary angioplasty was successfully performed, with a good final PCI result.
This case illustrates the practical application of a niche device (eg, excimer laser coronary angioplasty) as a useful tool to tackle calcified nodules and to allow a state-of-the-art PCI.
处理钙化结节仍是一项临床挑战。
一名77岁男性在经导管主动脉瓣植入术前检查期间接受了冠状动脉造影，显示右冠状动脉中段严重狭窄，并伴有一个可疑的造影钙化结节。准分子激光用于斑块预处理，并有助于随后在光学相干断层扫描冠状动脉内成像引导下进行经皮冠状动脉介入治疗（PCI）。成功实施了准分子激光冠状动脉成形术，PCI最终结果良好。
本病例说明了一种特殊设备（如准分子激光冠状动脉成形术）作为处理钙化结节和实现先进PCI的有用工具的实际应用。
