Hi doctor! My child is 1 year old, went to the doctor to have an ultrasound and diagnosed a membranous ventricular septal defect. So the doctor asked me if a 1-year-old child with a membrane septal defect needs surgery? What are the conditions for the baby to have surgery? Ask your doctor for advice. I would like to thank the doctor.

My baby is 5 months old. The baby had a fever after being vaccinated, so she took her to the hospital and discovered that she had a congenital heart defect, a 5mm ventricular septal defect. So the doctor asked me, is a 5-month-old baby with a 5mm ventricular septal defect need treatment and is it dangerous for a long time?
