Abstract : In this study, we discuss a female patient referred to cardiology with left ventricular hypertrophy at mid-ventricular segments resulting in a mid-cavitary obstruction and a left ventricular apical aneurysm. The patient had normal epicardial coronary arteries, but presented with recurrent cerebrovascular events. The patient had a positive family history for sudden cardiac death. Cardiac MRI detected positive features of left ventricular mid-cavity obstruction, left ventricular apical aneurysm and delayed gadolinium enhancement, with Holter monitoring assessment displaying segments of non-sustained ventricular tachycardia. Genetic analysis detected an myosin light chain 3 (MYL3) gene mutation. The patient will be referred to receive an implantable cardioverter defibrillator. The MYL3 gene mutation is a rare variant in patients with familial hypertrophic cardiomyopathy. To our knowledge, the presence of a left ventricular apical aneurysm has not been previously reported in literature concerning the MYL3 gene mutation. The presence of this abnormality further increases the risk of sudden cardiac death.
