If your child has patent ductus arteriosus (PDA), you may think you did something wrong during your pregnancy to cause the problem. However, the cause of patent ductus arteriosus isn't known.
Genetics may play a role in causing the condition. A defect in one or more genes might prevent the ductus arteriosus from closing after birth.
Clinical trials are research studies that explore whether a medical strategy, treatment, or device is safe and effective for humans.
