title: Transcatheter closure of double atrial septal defects with a single Amplatzer device.
abstract: Transcatheter closure of single secundum atrial defects has become the standard of treatment. The purpose of our study was to analyze the results of using a single Amplatzer device for closure of double atrial septal defects. Such defects were diagnosed in 41 out of 363 patients with atrial septal defects (ASDs) closed by transcatheter method. In 39, a single Amplatzer device was used. The size of the larger defect ranged from 5 to 18 mm, the smaller defect from 2 to 7 mm, with the distance between the borders of the communications ranging from 2 to 12 mm. We performed sizing and closure of only the larger defect. The mean size of implanted devices was 16.5 +/- 5.5 mm, equal to the stretched diameter of the main defect or 1-4 mm larger. The closure rate assessed by color Doppler flow examination was 61% after 24 hr, 78% after 1 month, 83% after 3 months, 86% after 1 year, and 95% after 2 years. If the distance between the two defects exceeded 7 mm, residual leaks were observed but tended to decrease and disappear with time. Selected patients with double atrial septal defects can be effectively treated with implantation of a single Amplatzer device.
