Idiopathic Left Ventricular Apical Aneurysm in a Sailor With Moderate Transient Chest Pain: A Unique Perspective on an Atypical Presentation in the Military Population.

ABSTRACT

Left ventricular (LV) apical aneurysm is a rare condition that carries a high risk of fatal cardiac rupture. Wall ruptures are an uncommon catastrophic complication after acute transmural myocardial infarction. Rarely is the rupture only contained by an adherent pericardium or hematoma creating a pseudoaneurysm. This clinical finding calls for emergent surgical intervention. If no ruptures are detectable and myocardium wall integrity is verified, the diagnosis of a true aneurysm can be made to be repaired via elective surgery. The etiological differential for a patient with an LV aneurysm in the setting of normal coronaries and in the absence of prior cardiac surgery remains broad, including traumatic, infectious, and infiltrative causes. In this case report, we demonstrate an atypical and rare presentation of an idiopathic LV apical aneurysm in a physically fit, active duty male in the U.S. Navy.
