ABSTRACT

Patent ductus arteriosus is a common malformation that accounts for approximately 10-12% of congenital heart disease. Patients commonly present in infancy with acyanotic congestive heart failure, with a left to right shunt. Embryologically, the ductus arises from the left VI aortic arch, connecting the proximal descending aorta to the left pulmonary artery. This structure typically closes in the first 24 hours of life. Persistence of the ductus is not well understood, but is related to prostagladins. Patients with PDA often have other associated structural abnormalities such as VSD, aortic stenosis, pulmonic stenosis, and aortic coartcation. PDA is more prevalent in patients with trisomy 18 and 21. Other common causes of left to right shunt include VSD, ASD, and endocardial cushion defect.
