Imaging findings of subvalvular aneurysm and associated congenital defects. (A) Echocardiogram in the plane of left ventricular outflow tract (LVOT) observed (highlighted) an aneurysm formation in the topography of subvalvular mitral–aortic fibrosa (arrow). (B, C, D and E) Cine-cardiovascular magnetic resonance to study the region of mitral–aortic intervalvular fibrosa. (B) Subaortic plane showing inner portion (*) of subvalvular pseudoaneurysm. (C) Coronal oblique plane, specific to the topography of the lesion, where the inner portion (*), neck (black arrow) and intrapericardial portion (**) of the pseudoaneurysm can be observed. (D) Valve plane during systole showing the opened bicuspid aortic valve. (E) LVOT plane individualizing mild aortic regurgitation, this plane does not have the same angle of echocardiography and therefore does not demonstrate the lesion. (F and G) Magnetic resonance angiography of the thorax. (F) Patent arteriosus ductus (large arrow) and coarctation of the aorta (arrow). (G) Anomalous pulmonary venous return of the left upper lobe vein into the innominate artery on the same side (arrow).
