Abstract
Cases (118) with coarctation of the aorta were reviewed; 46 showed unusual findings. In those 14 patients who died in the neo-natal period and infancy, 5 had an infantile type of coarctation. The most common complication in the 14 was patent ductus arteriosus, then interventricular septal defect and atrial septal defect. In those 7 patients over the age of 12 months who died before operation could be performed, the most common complication was bicuspid aortic valves. All were of the adult type coarctation. In the group of 3 patients operated upon but who died during surgery, the lesions were undiagnosed subaortic stenosis, mitral stenosis and calcific bicuspid stenosis. Four died at varying lengths of time after surgery. In the group which survived surgery the most common complication was patent ductus arteriosus. The remainder had subacute bacterial endocarditis and bicuspid valves, cerebral aneurysm, long coarcted segments, displacement of the right subclavian artery, inter-ventricular septal defect, proximal aneurysms, left sub-clavian artery involved in coarctation, and an absent transverse arch.
