  "summary_plain": "A device from Abbott that closes a hole between the two upper heart chambers (an atrial septal defect) through a catheter. NHLBI lists catheter repair and surgery as ways to close such a hole. The US FDA approved it in 2001 for atrial septal defects of the secundum type with echocardiographic evidence of the defect and clinical evidence of extra work for the right lower chamber (a left-to-right shunt of 1.5 to 1 or an enlarged right ventricle), and for closing the opening left after a fenestrated Fontan procedure. The FDA approval does not state an age range.",
  "summary_technical": "Amplatzer Septal Occluder (ASO) and Amplatzer Exchange System, FDA product code MLV, PMA P000039, approved 2001-12-05. The approval order lists secundum atrial septal defect closure for patients with echocardiographic evidence of an ostium secundum defect and clinical evidence of right ventricular volume overload, and closure of the fenestration in patients who had a fenestrated Fontan procedure. NHLBI lists catheter procedures among the ways to repair a simple defect of this kind when it does not heal by itself. No trial results are recorded here.",
