Excerpt
True left ventricular (LV) aneurysm usually results from weakening, thinning, and bulging of the full-thickness myocardial wall either from infarct, cardiac sarcoidosis, infective (cardiovascular syphilis, trypanosomiasis), or rarely congenital causes.
1 Pseudoaneurysms on the other hand are caused by rupture of the ventricular free wall with blood contained within the pericardium.
2 Transthoracic/transoesophageal echocardiography (EHCO), cardiac magnetic resonance imaging (MRI), cardiac computed tomography (CT), and equilibrium radionuclide ventriculography (ERNV) are the imaging methods used to establish the diagnosis and to differentiate between true or LV pseudoaneurysms.
3 We hereby report a patient with a large anterior LV aneurysm, causing a fixed perfusion defect and indentation on myocardial perfusion scintigraphy. The suspicion was raised on CT images acquired for attenuation correction and confirmation was obtained by ERNV. …
