Patient: Pre-existing heart disease, had pneumonia twice and was cured. Is such an atrial defect serious? Is there a need for surgery and what is the appropriate procedure? What is the approximate cost? The heart is in normal left position with consistent A-V connection and consistent V-A connection and left aortic arch. 2. The internal diameter of each atrium is still within the normal range. 3. 11mm diameter of pulmonary valve annulus, 2.0m/s laminar flow detected by Doppler at the valve orifice, 16mmHg CW estimated transvalvular pressure difference. 4. 10mm echogenic loss of atrial septum at the secondary orifice. The CFM showed left-to-right shunt in diastole. 5. The second and third cusps were movable, and Doppler detected mild regurgitation upstream of the tricuspid valve. The conclusion is: atrial septal defect (secondary foramen ovale type). Doctor: Your child’s heart ultrasound diagnosis is atrial septal defect 10mm, the child is currently 4 months old, although there are two histories of pneumonia, but because of the child’s young age, and the heart ultrasound suggests that the internal diameter of each atrium is within the normal range, so we recommend that you follow up regularly, generally speaking, if there are no obvious symptoms can be reviewed once in about 3 months, if there are symptoms then feel free to consult. Patient: Thank you for your reply, but I would like to ask: Is it because of the heart that my child sometimes cries inexplicably, as if he has pain somewhere? Is it possible for the child to recover on his own in April? What do I need to pay attention to in my child’s life? I’m looking forward to hearing from you! Doctor: There are many reasons for a child’s distressing noise, and it is difficult to say that it is necessarily related to heart disease. Generally speaking, if the diagnosis of atrial septal defect is confirmed, it is very unlikely to close naturally. Children with congenital heart disease should pay attention to reduce the possibility of respiratory infections.
