Representation of possible locations of the subvalvular ventricular aneurysm (*). (A) Subaortic, below the aortic annulus. Another presentation can be supra-aortic, in the left aortic sinus. Both near the left coronary artery. (B) Supra-aortic, perforation in the right aortic sinus insinuating itself into the interventricular septum (IVS). In general, when these defects are subaortic, they are complete and result in a defect of IVS. (C) Congenital alterations in fibromuscular junction of the mitral ring resulting in submitral aneurysm. (D) Perforation in fibrosa union between the base of the anterior mitral leaflet and the aortic root resulting in an aneurysm between the aorta and left atrium. This last example represents our case report, but we had an insinuation into the left ventricular outflow tract. Ao = aorta, AE = left atrium, CD = right coronary artery, TCE = left coronary artery; VD = right ventricle, VE = left ventricle.
