Objectives: We sought to provide clinical insights on the usage rate, indications, and in-hospital outcomes of the revived directional coronary atherectomy (DCA) catheter (Atherocut™) in a Japanese nationwide percutaneous coronary intervention (PCI) registry. Background: Debulking devices such as the revived DCA catheter have become increasingly important in the era of complex PCI. However, little is known about PCI outcomes using a novel DCA catheter in contemporary real-world practice. Methods: We analyzed 188,324 patients who underwent PCI in 1112 hospitals from January to December 2018. Baseline characteristics and in-hospital outcomes of patients with stable coronary artery disease or unstable angina who underwent PCI with or without the DCA were analyzed. Results: Overall, 1696 patients (0.9%) underwent PCI with the DCA during the study period, predominantly for left main trunk or proximal left anterior descending artery lesions under a transfemoral approach. Patients in the DCA group were younger and had fewer comorbidities such as hypertension, diabetes mellitus, and chronic kidney disease than patients in the non-DCA group. Stentless PCI using the DCA with drug-coated balloon angioplasty was a preferred treatment strategy in the DCA group (50.0%). Predefined in-hospital adverse outcomes, including mortality (0.2% vs. 0.3%, p = 0.446) and periprocedural complications (1.8% vs. 1.7%, p = 0.697), were comparable between the two groups, whereas the fluoroscopy time was longer and the total contrast volume was higher in the DCA group. Conclusions: In Japan, PCI using the revived DCA catheter is safely performed with low complication rates in patients with stable coronary artery disease or unstable angina.
