Coronary atherectomy has been around for many years, and the body of evidence for its use in complex calcified lesions has grown. Calcific coronary disease presents a particularly challenging clinical scenario in PCI, having poorer outcomes than noncalcified lesions. This study is the first to identify calcified nodules as an independent predictor of worse outcomes after atherectomy and PCI. Continued study of lesion characteristics will improve our understanding of PCI outcomes and help manage patients in the long-term after PCI and stenting.
经皮冠状动脉腔内血管成形术（PTCA）已有多年历史，其在复杂钙化病变中的应用证据也越来越多。在 PCI 中，钙化性冠状动脉疾病是一个极具挑战性的临床情况，其结果比非钙化病变更差。本研究首次发现钙化结节是血管成形术和 PCI 后结果恶化的独立预测因素。对病变特征的进一步研究将提高我们对 PCI 结果的认识，并有助于 PCI 和支架置入术后长期管理患者。
