Be careful of your child:

Kids who undergo cardiac catheterization to close an ASD usually spend the night in the hospital after the procedure. Those who have had a catheterization procedure should also be kept out of gym class or sports practice for a week; after a week, they can usually return to their normal physical activities, with their doctor's OK.

Kids who undergo surgery for their ASDs usually go home after a few days in the hospital if there are no complications. After surgical ASD repair, the main medical concern is the healing of the chest incision. In general, the younger patients are when they have their surgical repairs, the less pain they will have during recovery. The child will be watched closely for signs or symptoms that may indicate a problem. If your child has trouble breathing, is not eating, has fever, or redness or pus oozing from the incision, get medical treatment right away. In most cases, kids who have had ASD surgery recover quickly and without problems.
In the weeks following surgery or cardiac catheterization, your doctor will check on your child's progress. Your child may undergo another echocardiogram to make sure that the heart defect has closed completely. Kids who have undergone ASD repair will continue to have follow-up visits with the cardiologist.
Most children who undergo treatment for ASDs recover quickly — you may even notice that within a few weeks of treatment, your child is eating more and is more active than before surgery. However, some signs and symptoms may indicate a problem. If your child is having trouble breathing, call the doctor or take your child to the emergency department immediately. Other symptoms that may indicate a problem include:

• a bluish tinge or color (cyanosis) to the skin around the mouth or on the lips and tongue
• poor appetite or difficulty feeding
• failure to gain weight or weight loss
• listlessness or decreased activity level
• prolonged or unexplained fever
• increasing pain, tenderness, or pus oozing from the incision
