Question
Can a 4mm septal defect in a baby heal on its own?
Answer
Medication for congenital heart disease typically has no significant effect, and it is recommended to undergo repair surgery as soon as possible. Excessive ventricular workload may lead to heart failure, and treatment should be initiated early. Pain under the armpit in infants may indicate lymphadenitis, and it is advised to take the child to the hospital for examination and treatment.
