- Poor appetite
- Failure to gain weight
- Shortness of breath
- Easily tiring
- A persistent cough or wheezing with white or pink blood-tinged phlegm
- Swelling of the legs, ankles or feet
- Swelling of the abdomen

Some babies with the partial form of atrioventricular canal defect may not have any signs or symptoms for weeks, months, years or even decades, depending on the extent of the defect. But, anytime the signs or symptoms above start to appear, seek medical care.
