title: Unexplained double-chambered left ventricle associated with contracting right ventricular aneurysm and right atrial enlargement.
abstract: In this article, we describe a double-chambered left ventricle (LV) associated with a functional right ventricular (RV) aneurysm and right atrial (RA) enlargement in an asymptomatic 24-year-old woman with a family history of sudden cardiac death. We will discuss the differential diagnosis, genetic testing and possible prognostic implications.
