Most children who have PDAs live healthy, normal lives after treatment. Full-term infants will likely have normal activity levels, appetite, and growth after PDA treatment, unless they had other congenital heart defects.
For premature infants, the outlook after PDA treatment depends on other factors, such as:
Children who have PDAs are at slightly increased risk for infective endocarditis (IE). IE is an infection of the inner lining of the heart chambers and valves.
Your child's doctor will tell you whether your child needs antibiotics before certain medical procedures to help prevent IE. According to the most recent American Heart Association guidelines, most children who have PDAs don't need antibiotics.
Clinical trials are research studies that explore whether a medical strategy, treatment, or device is safe and effective for humans.
