Multiple idiopathic left ventricular aneurysms in a Japanese woman.

Idiopathic aneurysms of the left ventricle (LV) are uncommon in Western society. Multiple idiopathic LV aneurysms are distinctly unusual and are rarely reported. As with aneurysms of atherosclerotic origin, these entities may be associated with chest discomfort, congestive heart failure, cardiac dysrhythmias, and thromboembolic phenomena. We present the case of a Japanese woman living in the United States with chest discomfort, ventricular arrhythmias, and a previous transient ischemic attack who demonstrated four discrete LV aneurysms on ventriculography. Extensive evaluation demonstrated no clear cause for these aneurysms. The patient was treated conservatively with medical therapy and has continued to do well without adverse clinical sequelae.
