“…More contemporary devices for closure of interatrial communications have improved compared to older occluders. Advancements include a simpler deployment technique involving only venous access, higher complete closure rates, eradication of wire fractures, and reduction of device-related thrombus formation [2,7,11,12]. However, structural factors such as atrial septal aneurysms (ASA), a large discrepancy in thickness between septum primum and septum secundum, as well as long PFO tunnels may potentially lead to a mismatch between the individual anatomy and the technical design of the device.…”
