Abstract:
Transesophageal echocardiography (TEE) enables a more accurate visualization of left ventricular posterior aneurysms than transthoracic echocardiography due to the close proximity of the esophagus to the posterior ventricular wall. Therefore, TEE is essential for the accurate diagnosis of posterior aneurysm, particularly in urgent settings where preoperative assessments may be insufficient.
