Welcome to HCM,
I am happy that you want to know details about your baby,I am sure you must have been explained by the eminent doctors there.
With what information you have given your baby ha Congenital Heart Disease
, details of which are PDA stands for Patent ductus arteriosus
which is connection between left and right heart which allows some oxygenated blood to go back to lungs.
PAPVC Partial anomalous pulmonary venous connection which is some of oxygenated blood from lugs is connected to right side of heart.
As your baby is gaining weight take care of her and follow as advised by your cardiologist.
If they suggest surgery go for it later on.
Best of Luck.
