Hi, I had gone through your question and understand your concerns. Small hole in heart must a have closed by this age. You can do one Echocardiography to confirm that. The pain which your daughter having could be muscular related or retrosternal (under the chest) pain secondary to esophageal reflux (gastritis). Just avoiding the spicy food and antacid will help her reduce the pain. If pain is very severe and continues , she needs to checked by a pediatrician / paediatric surgeon. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing your daughter good health.
