question: Hello doctor, My baby boy is 3.5 months old. He was diagnosed with VSD when he was 2 months and his cardiologist asked for followup after a month. On out checkup his 3 mm VSD was closed, but the doctor discovered 6 mm ostium secundum ASD. He said that it can close spontaneously just like the VSD, so we have to check it after three months. We needed a second opinion so we consulted another cardiologist who echoed my baby and found out the same results, but he said that it is 6 mm superior secundum, but it will not close on its own cause of its position. Is it really true that my baby can get it closed only by open-heart surgery? I am worried about the scar and the side effects on my baby.
