A three-year-old girl was admitted to Hacettepe Children's Hospital du
e to sweating and poor feeding. Echocardiography demonstrated ostium p
rimum atrial septal defect with a cleft mitral valve, After two months
of medical follow-up with digitalis, she was subjected to open-heart
surgery, and a primum-type atrial septal defect with double mitral ori
fice was found. To avoid cresting acute mitral stenosis, the cleft was
only partially sutured and the septal defect was closed with a patch.
Her postoperative recovery was uneventful. It is emphasized that surg
ical intervention should be individualized in each case.
