![]() ![]() However, echocardiography is often adequate for the evaluating surgeon without need for further imaging. Echocardiogram and cardiac catherization confirm the diagnosis, and are also useful in defining the patient’s cardiac anatomy and defining other anomalies. In the neonate with severe disease, right ventricular hypertrophy may be seen while in older patients left ventricular hypertrophy may be seen with increased voltage and ST and T wave changes over precordial leads. ![]() A: Ductal coarctation, B: Preductal coarctation, C: Postductal coarctation. LocationThere are three type of aortic coarctations:Schematic drawing of alternative locations of a coarctation of the aorta, relative to the ductus arteriosus. This abnormality predisoposes to dissection or rupture in the area of the coarctation. Other cardiac anomalies including PDA and VSD may be associated, and the most important associated noncardiac abnormality is intracerebral aneurysm.Pathological findings include medial thickening and intimal hyperplasia forming a ridge that encircles the aortic lumen. There is an association with a bicuspid aortic valve with a reported incidence of 30-40% or more. Mean age for repair of a significant coarctation is around 17 years of age, thus detection by general pediatricians is very important.One-third of Turner's syndrome (XO) patients have a coarctation. IntroductionCoarctation of the aorta comprises 5-8% of all congenital heart disease, occurring 2-5 times more often in males than females.
