SymptomsBy Mayo Clinic staff
Patent ductus arteriosus symptoms vary with the size of the defect and the gestational age of the infant at birth. A small PDA may cause no signs or symptoms, and may go undetected for some time, even until adulthood. A large PDA can cause signs of heart failure soon after birth.
Your doctor may first suspect a heart defect during a regular checkup while listening to your baby's heart through a stethoscope.
A large PDA, found during infancy or childhood, may cause:
- Poor eating, poor growth
- Sweating with crying or eating
- Persistent fast breathing or breathlessness
- Easy tiring
- Rapid heart rate
- A bluish or dusky skin tone
When to see a doctor
Call your doctor if your infant or child:
- Tires easily when eating or playing
- Is not gaining weight
- Becomes breathless when eating or crying
- Always breathes rapidly or is short of breath
- Turns dusky or blue when crying or eating
