Left ventricular pseudoaneurysm: a case report and discussion on differential diagnoses.
Left ventricular pseudoaneurysm is a rare complication of myocardial infarction or cardiac trauma. We report a case of sudden death from rupture of such a lesion. Clinically, these lesions need to be distinguished from the other ventricular out-pouching lesions (true aneurysms and diverticula) because of their greater likelihood for rupture. Pathologically, apart from often being infarct-related, they are characterized by a narrow connection with the ventricular cavity and a fibrous outer wall that is devoid of myocardial tissue.
