Abstract
- The aim of this study was to investigate the impact of chronic total occlusion (CTO) on clinical outcomes in patients with calcified coronary lesions receiving rotational atherectomy (RA). This multi-center registry enrolled consecutive patients with calcified coronary artery disease who underwent RA during percutaneous coronary intervention (PCI) from 9 tertiary centers in Korea between January 2010 and October 2019. The primary outcome was target-vessel failure (TVF) which included the composite of cardiac death, target-vessel myocardial infarction (TVMI), and target-vessel revascularization (TVR). A total of 583 lesions were enrolled in this registry and classified as CTO (n = 42 lesions, 7.2%) and non-CTO (n = 541 lesions, 92.8%). The CTO group consisted of younger patients who were more likely to have a history of previous percutaneous coronary intervention or coronary artery bypass graft surgery. The incidence of the primary outcome was 14.1% and 16.7% for the non-CTO group and CTO group, respectively. The primary outcomes observed in the two groups were not significantly different (log-rank p = 0.736). The 18-month clinical outcomes of the CTO group were comparable to those of the non-CTO group in multivariate analysis. About 7% of patients requiring RA have CTO lesions and these patients experience similar clinical outcomes compared with those having non-CTO lesions. Use of RA for CTO lesions was safe despite higher procedural complexity.<br /> (© 2021. Springer Japan KK, part of Springer Nature.)
