The fifth heart chamber: Massive thrombotic left ventricular
pseudoaneurysm followed by successful ventricular aneurysmectomy
AbstractLeft ventricular pseudoaneurysm is a type of rare and lethal mechanical
complication derived from rupture of the ventricular free wall but
enclosed by the adherent pericardium or scar tissue. We present a rare
case of a massive pseudoaneurysm with a large thrombotic burden.
Echocardiography had a pivot role on early diagnosis of the
pseudoaneurysm allowing for appropriate downstream diagnostic testing.
Cardiac magnetic resonance confirmed a large pseudoaneurysm.
Furthermore, late gadolinium enhancement imaging demonstrated large
thrombotic burden within the pseudoaneurysm. Due to eminent risk of
rupture and danger of an embolic event our patient underwent a
successful ventricular aneurysectomy. The defect was closed with a 5cm
patch of bovine pericardium. An echocardiogram day 6 post-op showed an
intact patch repair with no residual pseudoaneurysm.
