We sought to evaluate clinical outcomes of RA. Materials and Methods: This multi-center registry enrolled patients who underwent RA during PCI from nine tertiary centers in Korea between January 2010 and October 2019. The primary endpoint was target-vessel failure (TVF; the composite outcome of cardiac death, target-vessel spontaneous myocardial infarction, or target-vessel revascularization). Results: Of 540 patients (583 lesions), the mean patient age was 71.4 \u00b1 0.4 years, 323 patients (59.8%) were men, and 305 patients (56.5%) had diabetes mellitus. Technical success rate was 96.4%. In-hospital major adverse cerebral and cardiac events occurred in 63 cases (10.8%). At 1.5 years, 72 (16.0%) of TVFs were occurred. We evaluated independent predictors of TVF, which included current smoker (hazard ratio (HR), 1.92; 95% confidence interval (CI), 1.17\u20133.16; p = 0.01), chronic renal disease (HR, 1.87; 95% CI, 1.14\u20133.08; p = 0.013), history of cerebrovascular attack (HR, 2.14; 95% CI, 1.24-3.68; p = 0.006), left ventricle ejection fraction (HR, 0.98; 95% CI, 0.97\u20130.999; p = 0.037), and left main disease (HR, 1.94; 95% CI, 1.11\u20133.37; p = 0.019). Conclusions: From this registry, we demonstrated acceptable success rates, in-hospital and mid-term clinical outcomes of RA in the DES era.<\/jats:p>","DOI":"10.3390\/medicina57070694","type":"journal-article","created":{"date-parts":[[2021,7,7]],"date-time":"2021-07-07T12:31:25Z","timestamp":1625661085000},"page":"694","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Clinical Outcome of Rotational Atherectomy in Calcified Lesions in Korea-ROCK Registry"],"prefix":"10.3390","volume":"57","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0149-5503","authenticated-orcid":false,"given":"Kyusup","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Cardiology, Daejeon St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea, Seoul 06591, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ji-hoon","family":"Jung","sequence":"additional","affiliation":[{"name":"Korea Institute of Toxicology, Daejeon 34114, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0658-4081","authenticated-orcid":false,"given":"Myunhee","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Daejeon St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea, Seoul 06591, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dae-Won","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Daejeon St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea, Seoul 06591, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mahn-Won","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Daejeon St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea, Seoul 06591, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9996-2346","authenticated-orcid":false,"given":"Ik-Jun","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Incheon St. Mary\u2019s Hospital, College of Medicine, The Catholic University of Korea, Incheon 21431, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jae-Hwan","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Cardiology in Internal Medicine, Chungnam National University Hospital, Daejeon 35015, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7101-0236","authenticated-orcid":false,"given":"Jang-Hoon","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Kyungpook National University Hospital, Daegu 41944, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5845-2232","authenticated-orcid":false,"given":"Sang-Rok","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Chonbuk National University Hospital, Jeonju 54907, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pil-Hyung","family":"Lee","sequence":"additional","affiliation":[{"name":"Asan Medical Center, Department of Cardiology, University of Ulsan College of Medicine, Seoul 05505, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seung-Whan","family":"Lee","sequence":"additional","affiliation":[{"name":"Asan Medical Center, Department of Cardiology, University of Ulsan College of Medicine, Seoul 05505, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ki-Dong","family":"Yoo","sequence":"additional","affiliation":[{"name":"Department of Cardiology, St. Vincent\u2019s Hospital, College of Medicine, The Catholic University of Korea, Seoul 06591, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kyeong-Ho","family":"Yun","sequence":"additional","affiliation":[{"name":"Regional Cardiocerebrovascular Center, Department of Cardiovascular Medicine, Wonkwang University Hospital, Iksan 54538, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hyun-Jong","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Sejong General Hospital, Bucheon 14754, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1548-4154","authenticated-orcid":false,"given":"Sung-Ho","family":"Her","sequence":"additional","affiliation":[{"name":"Department of Cardiology, St. Vincent\u2019s Hospital, College of Medicine, The Catholic University of Korea, Seoul 06591, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"(2018).
