Left ventricular pseudoaneurysm as a complication of LVAD explant

Abstract

Left ventricular (LV) pseudoaneurysms are a rare disease entity associated with a multitude of etiologies. We describe the radiographic findings of an LV pseudoaneurysm arising as a complication of a leaking left ventricular assist device (LVAD) closure device. Computed tomographic angiography (CTA) imaging demonstrated an apical LV wall defect with a preperitoneal collection of extravasated contrast. A review of the patient's surgical history revealed prior LVAD placement and explant with placement of an LV closure device. Familiarity with the radiologic manifestation of LV pseudoaneurysms is critical to establish a prompt diagnosis and facilitate timely therapeutic intervention.
