Transesophageal echocardiography is generally recommended when a very particular part of the heart needs to be imaged with a higher resolution. It allows us to see a better definition of the structures within the heart and can be particularly useful for the identification of clots or infections(Vegetation on valves). Echocardiogram (echo) utilizes ultrasound to take pictures of your heart's movements. A transesophageal echo (TEE) measure is a sort of echo that utilizes a long thin, tube (endoscope) to lead the ultrasound transducer down the esophagus ("food pipe" from the mouth to the stomach).
