Background: Over the past decades, significant advancements and innovations have occurred in the field of percutaneous atrial septal defect (ASD) closure using transcatheter-based devices. The Amplatzer septal occluder has been widely used since its Food and Drug Administration approval in 2001. Studies have shown its high success rate in closing ASDs. Since then, many other devices have been developed and used with high technical success and closure rates, with low rates of serious adverse events and device-related complications. When compared to surgery, percutaneous closure provides a less invasive approach with quicker recovery and reduced physical and psychological impact. Objectives: To demonstrate the effectiveness of using different devices for transcatheter ASD closure, emphasizing the success and complications obtained in our patients. Methods: Patients with congenital ASDs who underwent transcatheter closure using different devices were included. The primary endpoint was to determine the efficacy and safety of these devices and to determine the incidence of complications at follow-up. Two hundred and eighty-seven patients underwent ASD closure at a median age of 6 years (7 months-70 years). Results: Only minor complications occurred during catheterization. After a follow-up of 90 ± 67.7 months (up to 96 months), the closure rate was 98.6%, and the absence of atrioventricular block was 100%. Conclusions: Transcatheter ASD closure using percutaneous devices has proven to be safe and effective in most cases. However, careful patient selection and follow-up are necessary to minimize complications and ensure optimal outcomes.
