[Left-ventricular thrombosis in hypoplastic left heart syndrome: echocardiographic diagnosis].

Because of its fatal prognosis the hypoplastic left heart syndrome has to be distinguished from operable lesions with similar clinical presentation. In most cardiological centers the diagnosis is made solely by echocardiography. Additional diagnostic studies are performed only if echocardiographic findings are not standard. We report the echocardiographic findings in a case of hypoplastic left heart syndrome (aortic atresia, coarctation, mitral stenosis, hypoplastic left ventricle) where a thrombus formed inside the left ventricle in the third month of life.
