Rotational atherectomy (RA) has been widely used for percutaneous coronary intervention (PCI) to severely calcified lesions. As compared to other countries, RA in Japan has uniquely developed with the aid of greater usage of intravascular imaging devices such as intravascular ultrasound (IVUS) or optical coherence tomography (OCT). IVUS has been used to understand the guidewire bias and to decide appropriate burr sizes during RA, whereas OCT can also provide the thickness of calcification. Owing to such abundant experiences, Japanese RA operators modified RA techniques and reported unique evidences regarding RA. The Task Force on Rotational Atherectomy of the J apanese Association of Cardiovascular Intervention and Therapeutics (CVIT) has now proposed the expert consensus document to summarize the contemporary techniques and evidences regarding RA.
旋磨术（RA）已广泛应用于经皮冠状动脉介入治疗（PCI）严重钙化病变。与其他国家相比，日本的 RA 独特发展，得益于血管内成像设备（如血管内超声（IVUS）或光相干断层扫描（OCT））的更大应用。IVUS 用于了解导丝偏倚，并在 RA 期间决定合适的钻头尺寸，而 OCT 还可以提供钙化的厚度。由于这些丰富的经验，日本 RA 操作人员改进了 RA 技术，并报告了有关 RA 的独特证据。日本心血管介入治疗学会（CVIT）的 RA 工作组现已提出专家共识文件，以总结 RA 的当代技术和证据。
