To the Editor
We read with great interest the article by Neirotti and colleagues describing the interesting and well-documented case of a 3-month-old baby in heart failure due to severe congenital coarctation of the distal thoracic aorta [1].
The references mentioned in the above article are mostly related to abdominal aortic coarctation. Despite its rarity, this curious location of an obstruction was first described in 1835, according to Abbott [2]. As far as we know, there were only 12 cases published by 1993, when we described the case of a young man successfully operated on for this lesion [3]. In our case, a high index of suspicion of coarctation and an unobstructed aorta during cross-sectional echocardiography led to cardiac catheterization. During the procedure, a classic coarctation was not found. The obstruction was located after a second contrast injection in the lower thoracic aorta.
We agree with Dr Neirotti and associates when they say that the whole aorta should be assessed echocardiographically, especially when coarctation is clinically suspected and not found at its usual site.
