Aims: To evaluate the method of catheterization occlusion of the atrial septal defect (ASD) by the Amplatzermethod. To find out differences between catheterization and surgical occlusion in the efficiency, functional resultsand occurrence of complications as well as the cost.Methods: The centrally localized defect of the atrium septum of the secundum type was closed by theAmplatzeroccluders in 55 selected patients in the years 1998 to 2002. Themedian age of the patients was 8.5 years (6.2 - 13.5,25 percentile/75 percentile). The mean body weight was 25.8 kg (20.3 - 51.9). The diameter of the atrium septumdefect was 12.0 mm (10 - 13.9); it was in the range of 5 to 22 mm. The mean period of observation was 372 days(108 - 750) with the range of two days to 3.7 years. The results were compared with 153 patients, whose ASD of thesecundum type was occluded by surgery in the same period of time.Results: The occluder was successfully implanted in all 55 patients, where the decision of this intervention wasaccepted. Immediately after the ASD occlusion there was a significant reduction of left-right shunt from 38 %Qp(24 - 48) to two %Qp (P
