Incidental diagnosis of a large left ventricular pseudoaneurysm

Abstract

Left ventricular pseudoaneurysm is a rare complication of myocardial infarction and represent a myocardial rupture contained within a pericardial space limited by adhesions. Differentiating it from a left ventricular aneurysm can be a real diagnostic challenge. We report a case of a 50-year-old man admitted for symptoms of left heart failure. Transthoracic echocardiography and cardiac computed tomography scan incidentally showed a large lateral left ventricular pseudoaneurysm measuring 75/50 mm in diameter. Patch closure was carried out under cardiopulmonary bypass. Postoperative follow up was uneventful. This case demonstrates the increasing detection of «incidental» left ventricular pseudoaneurysm with more frequent use of multimodality imaging techniques including cardiac CT scan.
