[Natural course of an aortic coarctation in a child].

Aortic coarctation is a frequent congenital heart disease that presents in form of two entities, the infant type and the child or adult type. The infant type is the most frequent and manifests acutely by heart failure or shock. The second one shows a slow and progressive course with no or few initial symptoms. For that reason, the diagnosis is usually missed until symptomatic arterial hypertension or hypertrophic cardiomyopathy develop. We report the case of an initially asymptomatic boy in whom the development of an aortic coarctation could be precisely documented over a period of 10 years by repeated bidimensional and Doppler echocardiography. The patient underwent successful balloon angioplasty of the aortic isthmus and stent implantation. This case points out the importance of strict follow-up in any young child in whom an even mild anomaly of the aortic arch is detected. This is critical in order not to miss an aortic coarctation that influences significantly morbidity in adulthood.
