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\u2010DCA group. Stentless PCI using the DCA with drug\u2010coated balloon angioplasty was a preferred treatment strategy in the DCA group (50.0%). Predefined in\u2010hospital adverse outcomes, including mortality (0.2% vs. 0.3%, <jats:italic>p<\/jats:italic>\u2009=\u20090.446) and periprocedural complications (1.8% vs. 1.7%, <jats:italic>p<\/jats:italic>\u2009=\u20090.697), were comparable between the two groups, whereas the fluoroscopy time was longer and the total contrast volume was higher in the DCA
