What is the difference between a TEE and TTE?
TEE is considered more sensitive for the detection of major cardiac sources of emboli such as left atrial thrombus, aortic atheroma, valve abnormalities, atrial septal abnormalities and cardiac tumours. TTE is more suited for the visualization of left ventricular thrombus.
What procedure is a TTE?
A transthoracic echocardiogram (TTE) is a test that uses ultrasound (sound waves) to create images of your heart. It's the most common type of echocardiogram (echo). The test helps healthcare providers see your heart, its four chambers, the four heart valves and nearby blood vessels.

Is TTE or TEE more accurate?
Recently, transesophageal echocardiography (TEE) has been proven superior to transthoracic echocardiography (TTE) for the detection of potential sources of cardiac embolism in patients with previous stroke. The diagnostic yield of TEE for the detection of a cardiac source of embolism is estimated between 40% and 60%.

How does TTE work?from en.wikipedia.org
TTE is inherently limited in what it is capable of doing. Notably, it must be used through the skin, and ultrasound waves must go through skin and soft tissue before reaching the heart. This is in contrast to transesophageal echo (TEE) in which the probe is directly behind the left atrium in the esophagus and has far less tissue to penetrate, which means images from TEE are far superior in quality. Extremes in body sizes (obesity and cachexia) limit the acoustic windows and degrade the image quality of TTEs.
