In Japan, Amplatzer™ duct occluder I (ADO I), Amplatzer™ duct occluder II (ADO II), and Amplatzer Piccolo occluder™ (Piccolo) were included in insurance in 2009, 2019, and 2020 respectively. Since then, the occlusion of patent ductus arteriosus (PDA) using coils has become less common. However, knowledge and information about the anatomy and pathophysiology of PDA are very important for catheter interventions for PDA using other devices. Moreover, experiences of PDA coil occlusion have provided information related to catheter interventions using coils for other vessels. We describe our knowledge and experience and provide tips to improve PDA coil occlusion, focusing on 1) indications for PDA coil occlusion in the device era, 2) anatomy and pathophysiology of PDA, 3) performances of coils when deployed in the PDA, 4) complications of PDA coil occlusion, and 5) procedures useful for the closure of moderate or severe PDA.
