Abstract

Left ventricular (LV) pseudoaneurysm is a serious complication of periannular extension of infective endocarditis (IE). Because pseudoaneurysm carries a high risk of rupture, its detection and evaluation are crucial for patient management and surgical planning. We report 2 cases with LV pseudoaneurysms, one near the aortic valve and the other near the mitral valve, which were caused by IE and treated successfully. In both cases, cardiac multidetector-row computed tomography enabled detection of the LV pseudoaneurysm and a detailed demonstration of its anatomic relationship with surrounding structures, which helped guide surgical planning.
