@entity1 @entity118 @entity358
BACKGROUND: Percutaneous occlusion of secundum type @entity118 with an Amplatzer device is an effective treatment alternative. However, there is little information about the use of this treatment for large defects. @entity1 AND METHOD: We retrospectively analyzed the initial and follow-up findings in 31 @entity1 aged 41 18 years who had large @entity118 (>= 30 mm diameter). Mean defect diameter evaluated by the balloon occlusion method was 33.4 3.4 mm (range, 30-40 mm). In all @entity1 we attempted the implantation of an Amplatzer septal occluder. RESULTS: The implant was successful in 23 @entity1 (74%); 3 of whom had a double orifice. The size of the device was 34 3 mm diameter (range, 30-38 mm). Combined associated procedures were @entity358 in 3 @entity1 and coronary stent implantation in 1. In 4 out of 8 @entity1 where we failed, the implant was attempted but the device was unstable so we decided to retrieve it; in the remaining 4 @entity1 , balloon measurement alone contraindicated the procedure. All @entity1 did well, but one had cardiac tamponade during the procedure that was resolved in the catheterization laboratory. After 15 12 months of follow-up all 31 @entity1 were alive and those who had functional limitation before treatment remained stable, with significant clinical improvement. CONCLUSIONS: Percutaneous device occlusion of large @entity118 is feasible and effective in most @entity1 .
