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.

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
