Apical Aneurysm in Chagas Heart Disease

Abstract

Coronary CT angiographic and (C) cardiac MR image (Movie 1) in a 66-year-old woman with chronic Chagas disease, heart failure, and progressive dyspnea. The coronary CT angiographic images show a large apical aneurysm (apical lesion) of the left ventricle (arrowheads) but no obstructive coronary artery disease. The cardiac MR image also depicts this aneurysm (arrowheads) and apical dyskinesia (Movie 2). Late gadolinium enhancement image shows transmural enhancement of the apical segments and the true apex, without thrombus (C).
