[Left ventricular aneurysm in an eight-year-old girl (author's transl)]

A female patient with a heart murmur typical for mitral insufficiency that was first heard, when she was 17 months old, is reported. In the ECG flattened T-waves in the left praecordial leads are seen. Because of a typical x-ray seven years later the diagnosis of leftventricular aneurysm was suspected, guaranteed by angiocardiography and because of repeated supraventricular tachycardias the congenital aneurysm was operated. A differentiation between congenital diverticulum and congenital aneurysm is established, the clinical symptoms of this malformation and the therapeutic consequences are discussed.
