Outcomes of device closure of large and small secundum atrial septal defects (ASDs) as related to rim anatomy with the Amplatzer atrial septal occluder were compared. Rim adequacy (> or = 5mm) of the anterior, inferior, posterior, and superior rims was determined using transesophageal echocardiography. Balloon-stretched defect size defined patients into two groups: group 1, < or = 25 mm (n = 138); group 2, > 25 mm (n = 34). Rim deficiency (n = 62) was more frequent in group 2 compared to group… CONTINUE READING
