Abstract:
We describe an elderly patient undergoing ablation for atrial fibrillation in whom, two-dimensional transesophageal echocardiography showed a mass-like lesion in or adjacent to left atrial appendage (LAA). This mass-like effect was produced by en face visualization of the top of a LAA lobe in the presence of a small effusion in the transverse sinus of the pericardium.

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...
