Patent ductus arteriosus symptoms vary with the size of the defect and whether the baby is full-term or premature. A small PDA might cause no signs or symptoms and go undetected for some time — even until adulthood. A large PDA can cause signs of heart failure soon after birth.
Your baby's doctor might first suspect a heart defect during a regular checkup after hearing a heart murmur while listening to your baby's heart through a stethoscope.
A large PDA found during infancy or childhood might cause:
- Poor eating, which leads to poor growth
- Sweating with crying or eating
- Persistent fast breathing or breathlessness
- Easy tiring
- Rapid heart rate
