Trans-esophageal echocardiography (TEE) aims at studying the structure and function of the heart. It is performed through introducing a probe of 1 cm in diameter through the mouth into the esophagus.
The close position of the esophagus to the heart allows the TEE to obtain a better visualization of heart structures. It can study the structure and function of the heart accurately, and diagnose congenital heart disease, cardiac masses, infection of heart valves and aortic dissection.
This procedure is suitable for anyone, except those who have swallowing problem, and history of operation in pharynx or esophagus.
