Abstract:
Left atrial appendage (LAA) filter implantation was attempted in an 89 year old male. The LAA size was estimated by transesophageal echocardiography (TEE). Complete LAA obliteration was not achieved. LAA angiography suggested that the LAA was multilobed, likely separated by a thin septae not seen with TEE. MRI or CT may be more appropriate imaging modalities to define LAA anatomy.

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...
