<I>Objective</I>: Atrial septal defects and patent foramen ovale can now be closed percutaneously. This report describes our initial and follow-up experience, especially in relation to efficacy and complications. <br><I>Methods</I>: During a 2-year period, seven atrial septal defects and one patent foramen ovale were closed. The Amplatzer&lt;sup&gt;(R)&lt;/sup&gt; atrial septal defect occluder was used in five, the Cardioseal&lt;sup&gt;(R)&lt;/sup&gt; device in two and the Amplatzer<sup>(R)</sup> patent foramen ovale occluder in one. A compliant sizing balloon was used to assess the stretched diameter of the defects. <br><I>Results</I>: Percutaneous closure was successful in all patients. The median age was 5.4 years (range: 3.7-16.6 years) and median weight was 18 kg (range: 14-65 kg). The mean duration of the procedure was 2.3 hours. There were no acute complications. Patients were followed up for a mean of 1.1 years. One child experienced severe headaches and another developed an atrial flutter and a small leak 7 months after implantation, both of which resolved. <br><I>Conclusion</I>: Percutaneous closure of atrial septal defects and patent foramen ovale is effective and safe. In selected children, this may be offered as an alternative to surgery.
