Does any of this apply?
Book an appointment
Routine appointments remain important when there are no new symptoms.
These visits monitor heart function, blood flow, rhythm, oxygen levels, growth, and the condition of previous repairs.
Every sign above is quoted from the sofidex article on Pulmonary atresia. If you are not sure, err upward — it is always reasonable to be checked.
