Your daughter is eating well and weight is normal and she is able to take part in regular activities is a very strong indication your child is making a full recovery without any complications. The heart will return to normal size with the reduced workload for the heart due to blood volume overload caused by PDA ...if the left ventricle is pathologically enlarged there would be a faster than normal heart rate, shortness of breath, muscle fatgue, etc. indicating the heart cells are not receiving a good supply of oxygenated blood. I am assuming the heart enlargement is not heart muscle disease, but was/is dialted due to being overworked by the additional blood volume from PDA.
I had an enlarged heart sometime ago, and with medication the heart returned to normal size and functionality. Is your daughter taking any medication? And some medications can cause sweating.
Thanks for sharing, and if you have any further questions or comments you are welcome to respond. I wish your daugther well going forward. Take care,
Ken
Long-term complications from surgery are rare. However, they can include narrowing of the aorta, incomplete closure of the PDA, and reopening of the PDA
In general, symptoms that indicate that surgery is needed are:
•difficulty breathing because the lungs are wet, congested, or fluid-filled (congestive heart failure)
•problems with heart rate or rhythm (arrhythmias)
•excessive work load on heart that interferes with breathing, feeding, or sleeping
Fast breathing, working hard to breathe, or shortness of breath. Premature infants may need increased oxygen or help breathing from a ventilator.
Poor feeding and poor weight gain.
Tiring easily.
Sweating with exertion, such as while feeding.
