A PDA is a congenital anomaly resulting from the persistence of the distal portion of the left sixth aortic arch. The persistence of the duct after birth can have detrimental effects on the cardiovascular and pulmonary systems, depending on the size of the duct and the volume of blood flow through it. The resulting volume overload can lead to enlargement and failure of the left cardiac chambers, as well as pulmonary artery hypertension. In adults, percutaneous intervention is often preferred over surgical closure due to factors such as ductal calcification, aortic fragility, and elevated PAP. Approved devices for PDAPatent ductus arteriosus (PDA) closure include ADO types I and II, as well as certain coils. However, the variability in the shape and size of the duct in some cases makes closure with standard devices challenging. As a result, the off-label use of other devices, such as vascular plugs, muscular ventricular septal occluders, and atrial septal occluders, may be necessary.

摘要

A PDA is a congenital anomaly resulting from the persistence of the distal portion of the left sixth aortic arch. The persistence of the duct after birth can have detrimental effects on the cardiovascular and pulmonary systems, depending on the size of the duct and the volume of blood flow through it. The resulting volume overload can lead to enlargement and failure of the left cardiac chambers, as well as pulmonary artery hypertension. In adults, percutaneous intervention is often preferred over surgical closure due to factors such as ductal calcification, aortic fragility, and elevated PAP. Approved devices for PDAPatent ductus arteriosus (PDA) closure include ADO types I and II, as well as certain coils. However, the variability in the shape and size of the duct in some cases makes closure with standard devices challenging. As a result, the off-label use of other devices, such as vascular plugs, muscular ventricular septal occluders, and atrial septal occluders, may be necessary.
