[Mitral incompetence as presenting feature of idiopathic left ventricular aneurysm (author's transl)]

A further case of the exceptionally rare condition of idiopathic left ventricular aneurysm is reported in which the lesion was detected in a most unusual manner. The patient, a young 22-year-old negro woman, had been admitted for investigation of a mitral incompetence. The true diagnosis was established by angiography, which demonstrated a large multilobular left ventricular aneurysm, also communicating with the left auricle, this being the cause of the mitral incompetence. Surgical correction of the lesion suppressed the mitral leak without touching the normal mitral apparatus.
