概要	AIMS Rotational atherectomy (RA) is a promising strategic option for technical success of percutaneous coronary intervention (PCI) to severely calcified lesions. However, long-term clinical prognosis after RA has not been fully discussed in the drug-eluting stent (DES) era. PARIS score can separately predict embolic and bleeding events after PCI. We aimed to validate PARIS score in predicting clinical outcomes of patients who were treated with RA. METHODS AND RESULTS Total of 404 patients undergoing PCI with RA between 2004 and 2013 was enrolled. Median follow-up period was 1,521 days. The rate of coronary thrombotic events (CTEs: stent thrombosis and myocardial infarction) and major adverse cardiac events (MACE: CTEs, cardiovascular death, and target vascular revascularization) were compared among patients with PARIS-CTEs low (n=123), intermediate (n=109), and high (n=172) score group. Additionally, incidence of major bleeding (MB) was also compared among PARIS-MB low (n=35), intermediate (n=159), and high (n=210) score group.As a result, Kaplan-Meier analysis revealed that both rates of CTEs and MB were comparable among the groups (4-year CTEs: 4.2%, 9.2%, 7.5%, p=0.11, MB: 7.2%, 5.5%, 10.0%, p=0.22). In contrast, MACE rate was significantly higher in the higher PARIS-CTEs score group (4-year MACE: 22.8%, 44.4%, 52.5%, p<0.001). CONCLUSIONS PARIS score may predict long-term MACE, but not each of CTEs or bleeding events in patients after RA in the DES era.
