What is the prognosis after PDA closure?
Closing the PDA restores normal circulation to the heart and reduces the risk of endocarditis, pulmonary hypertension, aneurysm formation and death. But closing the defect may not reverse the damage already done to the heart, such as congestive heart failure, pulmonary vascular disease or calcium deposits at the site of the defect. Endocarditis prophylaxis (antibiotics) is recommended for 6 months following closure of a PDA or for life if any residual defect is present.
Patients with repaired PDAs should remain under the care of a cardiologist experienced in adult congenital heart problems.
