Patient: Our baby was born with an atrial defect of 3.4 MM, and now you have checked that it is 2.3 MM. I would like to ask what is the chance that it will grow well afterwards? If not, when is it appropriate to do interventional surgery? What is the approximate cost of doing it in the hospital? Thank you! Specialist: Usually it grows well within one year, if it does not grow well, you can consider interventional treatment at 2.5 years old, the cost is about 35,000. Patient: Hello! Sorry to ask you again. I don’t know if there are any vaccinations that can’t be carried out in the case of our baby now. In particular, this six-month inoculation called cerebral flow says that heart disease prohibits inoculation. The last time I asked you for a checkup, you said it would be fine to raise it normally. We don’t know if it’s okay to vaccinate or not. I’m waiting for your reply, thank you! Expert: Congenital heart disease itself is not a contraindication to vaccination.
