Symptoms & Signs
What are the signs and symptoms of the condition?
Serious cases of patent ductus arteriosus are diagnosed at birth. The infant will have abnormal pulses and heart murmurs that can be found during a physical exam. Sometimes a person with patent ductus arteriosus has no symptoms until middle age. In severe cases, the strain on the heart and lungs can cause congestive heart failure, a condition in which the weakened heart cannot pump blood effectively.
