Identical Twins With Hypertrophic Cardiomyopathy and Apical Aneurysm

Left ventricular apical aneurysms, in absence of coronary artery disease, occur in approximately 1% of patients with hypertrophic cardiomyopathy (HC). Identical twins, age 44 years, are presented with HC and identical LV morphology, including apical aneurysms. These cases demonstrate a genetic predisposition to the development of apical aneurysm, as well as overall LV morphology, in patients with HC.
