Most commonly it is associated with bicuspid aortic valves and to a lesser degree to other aortic abnormalities such as aortic root dilatation and aneurysms of the sinuses of Valsalva. Even though coarctation of the aorta can be associated with shunts lesions such as patent ductus arteriosus and ventricular septal defects, it has rarely being reported to be associated with atrial septal defects.
