hello doctor, my daughter is just 2 months old. Just 2 days after her birth, doctors found heart murmer . On further diagnosis, doctor's confirmed that she is suffering from pulmonary artresia. As her pulmonary artery is almost missing, doctors are advising us to wait for some months before going for surgery. But during this time, if her oxygen saturation level goes down, then they would be helpless. I am not sure as what to do? Can she survive for few months without any medication. Please let me know
