The authors present a case of adult aortic coarctation with two associated intercostal aneurysms and poor left ventricular function. The intercostal aneurysms appear, radiographically, as a subclavian aneurysm. The case illustrates, in aortic coarctation, the potential difficulty in defining the anatomy of the associated vascular aneurysms. The authors also demonstrate that the left ventricular function markedly improves after resection of the aortic coarctation.
