Clinical impact of transcatheter closure of secundum atrial septal defects with the double umbrella device.
The clinical impact of transcatheter closure of the isolated secundum atrial septal defect was reviewed. Closure by echocardiographic evaluation was 23 +/- 14% at 6 months, 49 +/- 16% at 2 years, and 64 +/- 16% at 4 years, and right ventricular end-diastolic dimensions in patients without residual shunts did not differ significantly from those with residual shunts.
