[Percutaneous closure of atrial septal defects using the Amplatzer device].

Percutaneous closure of an atrial septal defect (ASD) was undertaken in 10 patients aged from 3 to 33 years. The Amplatzer device was introduced intravenously and positioned under fluoroscopic and echographic control. The size of the ASD varied from 13 to 20 mm and that of the devices from 15 to 32 mm. One patient was operated for the removal of an improperly positioned device and closure of the ASD. All the other patients were discharged 24 hours after the procedure with successfull closure of the ASD. Complications were benign: spontaneously regressive arrhythmias (1 case) and migraines (2 cases). Our series reflects the experience of others, showing the faisability and efficiency of the procedure. Tridimensionnal or intracardiac echocardiography may improve this technique in the future.
