Cardiomyopathy is usually present in infants with critical coarctation, especially if additional levels of left heart obstruction, such as aortic stenosis or subaortic stenosis, are present. Some patients may have changes of endocardial fibroelastosis that result in chronic dilated cardiomyopathy, requiring medical management or, in rare cases, cardiac transplantation. Hypertrophic cardiomyopathic changes also may occur, predisposing the patient to subendocardial ischemia, arrhythmias, or congestive heart failure (CHF) related to diastolic dysfunction.
