    Abstract Background: Although transcatheter closure of atrial septal defect (ASD) is safe and effective for patients with sufficient rim, ASD patients with absent and/or malaligned aortic and/or superior rim have higher risks of device embolization and cardiac erosion. We have treated such high-risk patients using a Figulla Flex II (FFII) device shaped flared and straddling behind the aorta because this method would avoid such serious complications. However, its long-term efficacy and safety remain unclear. Therefore, the midterm efficacy and safety of this method were studied. Methods: We retrospectively evaluated the outcome of 47 consecutive patients with such rim (age 6–73 years,… More >
