OBJECTIVES: We sought to investigate the 1-year outcomes, including all-cause and cardiovascular mortality, major adverse cardiovascular events (MACEs), and major bleeding, of patients undergoing percutaneous coronary intervention (PCI) with or without the revived directional coronary atherectomy (DCA) catheter in a Japanese nationwide registry.
BACKGROUND: Clinical data regarding the midterm outcomes of patients undergoing PCI with DCA are scarce in contemporary real-world practice.
METHODS: We analyzed the data of 74,764 patients who underwent PCI at 179 hospitals from January 2017 to December 2018. The baseline characteristics and 1-year outcomes of patients with stable coronary artery disease or unstable angina who underwent PCI with or without DCA were assessed.
RESULTS: Overall, 431 patients (0.6%) underwent PCI with DCA. Patients in the DCA group were younger and predominantly male, with fewer comorbidities than patients in the non-DCA group. Stentless PCI with DCA following additional drug-coated balloon (DCB) angioplasty was the dominant strategy in the DCA group (43.6%). One-year outcomes, including all-cause mortality (1.2% in the DCA group vs. 2.5% in the non-DCA group, respectively, p = 0.075), cardiovascular death (0.9% vs. 1.0%, p = 0.69), MACEs (1.9% vs. 1.8%, p = 0.96), and nonfatal major bleeding requiring readmission (1.2% vs. 1.4%, p = 0.62), were comparable between the two groups. In the DCA group, 1-year outcomes were comparable, regardless of whether the stent or DCB was used.
CONCLUSIONS: One-year clinical outcomes after PCI with DCA in patients with stable coronary artery disease or unstable angina are acceptable, regardless of stent use.
