Coarctation of the aorta is a pathology characterized by  narrowing of the aorta, with consequent obstruction of its flow; Located more frequently at the level of the descendingthoracic aorta distal to theorigin of the left subclavian, and in the posterior wall of the artery. It accounts for approximately 5.1% (3-10%) of congenital heart defects and constitutes the eighth cardiac malformation in order of frequency. The clinical presentation of aortic coarctation is very varied and depends on the severity of the lesion and its possible association with other cardiac abnormalities. It emphasizes the type of infant and adult type, the first being the one with the highest morbidity and mortality. Two-dimensional echocardiography and Doppler echocardiography are the fundamental diagnostic method for aortic coarctation. Magnetic resonance angiography (MR) allows a detailed evaluation of the aorta through a three-dimensional reconstruction that clearly shows its defects. On the other hand, the multi-cut TAC allows the three-dimensional visualization of the arc from multiple planes, but as an inconvenience it has the emission of radiation. Cardiac catheterization is more than a diagnostic means, a therapeutic one in which not only the location and extent of the alveolar area, the presence of associated lesions and / or collateral circulation is  demonstrated, but also allows the obtaining of a knowledge Reliability of the severity and hemodynamic repercussion of the same. The treatment of this pathology can be initially medical, but definitively by interventional cardiac catheterization and less frequently surgical correction.
