Patient's question:
Doctor, what is the difference between atrial septal defect and patent foramen ovale? Color Doppler MRI shows patent foramen ovale. Another doctor from a different hospital saw the color Doppler MRI results and said it was an atrial septal defect. I don't know what the difference between the two is?Doctor's answer:
Atrial septal defect is a common type of congenital heart disease in children. Small defects may be asymptomatic. Heart murmurs can only be discovered during a physical examination, and small defects can naturally close. Atrial septal defect and patent foramen ovale are common types of congenital heart disease in children. If asymptomatic, they can receive follow-up before school. Patent foramen ovale can be observed for 1 year, and it may close within the first year.
