Surgical repair of patent ductus arteriosus PDA in adults is performed by left lateral thoracotomy, but may require a midline sternotomy, extracorporeal circulation, aortic cross-clamping, and other measures, with recovery in an intensive care unit. Surgical risk may be further increased by anatomic and histologic changes in the ductus, including calcification, aneurysm, diverticulum, shortening, and friability 1,2 and, therefore, percutaneous occlusion as a first-line treatment is a valid option. If left untreated, PDA can foster the development of infective endarteritis, Eisenmenger syndrome, and other conditions, with an annual mortality rate of 1.

Patent ductus arteriosus PDA is a congenital heart defect — a structural heart problem that is present at birth. Patent ductus arteriosus is an abnormal connection between the aorta and the pulmonary artery in the heart. While the baby is in the womb, the aorta and the pulmonary artery are connected by a temporary blood vessel, the ductus arteriosus, as part of the normal fetal circulation. The ductus arteriosus streamlines fetal circulation by flowing blood directly to the aorta, bypassing the lungs.

An unclosed hole in the aorta. Before a baby is born, the fetus's blood does not need to go to the lungs to get oxygenated. The ductus arteriosus is a hole that allows the blood to skip the circulation to the lungs.

Large PDAs are rarely discovered in the adult patient. If present, they are often associated with high pulmonary blood pressures and pulmonary vascular obstructive disease PVODwhich may be the result of the left to right shunt the movement of blood from the aorta into the pulmonary artery through the open ductus PDA. Diagnosis of a small PDA is often difficult because of the lack of major symptoms.

The ductus arteriosusalso called the ductus Botalliis a blood vessel in the developing fetus connecting the trunk of the pulmonary artery to the proximal descending aorta. It allows most of the blood from the right ventricle to bypass the fetus's fluid-filled non-functioning lungs. Upon closure at birth, it becomes the ligamentum arteriosum.

From week 6 of fetal life until birth, the ductus is responsible for most of the right ventricular outflow. Normally, functional closure of the ductus arteriosus occurs by about 15 hours of life in healthy, full-term infants. Patients with a moderate left-to-right shunt may remain asymptomatic for years.

Patent ductus arteriosus PDA is a fairly common congenital heart defect that occurs in about 3, newborns every year in the United States, according to the Cleveland Clinic. Symptoms may be minimal or severe. In rare cases, the defect can go undetected and can exist in adulthood.
