Transesophageal echocardiography is an imaging procedure . Sound waves are passed from an ultrasound probe in the esophagus (tube from mouth to stomach) to provide clearer images of the heart
Reasons for Procedure
Transesophageal echocardiography is performed to detect abnormalities in the heart. This may include enlarged heart, thickening of the heart walls, abnormal valve function, infection, blood clots, and more.

Risk Factors for Complications During the Procedure
You may be at higher risk for complications if you have known esophageal problems, esophageal obstruction, or have received radiation therapy to the esophagus.
What to Expect
Prior to Procedure
Typically, you will be asked not to consume any alcohol for several days before the procedure because it may interfere with the type of sedative used. It is sometimes also required that you do not eat or drink anything a few hours before the procedure.
A mild sedative is administered to help you relax, but you remain awake throughout the procedure. A topical anesthetic may also be applied to the back of the throat.
Description of the Procedure
You will be asked to lie on your side in a hospital gown. A transducer, a device that emits sound waves, is slid down the throat and into the esophagus until it is near the heart. The transducer emits sound waves that bounce off of a section of the heart. These projected sound waves are translated into images of the heart.
Transesophageal echocardiography is an outpatient procedure, which means a hospital stay is not required. You will need someone to drive you home following the procedure.
How Long Will It Take?
The process takes between 30-60 minutes.
Will It Hurt?
There is mild discomfort during the procedure, which usually results in a sore throat.
Reactions to the anesthetic are possible, as are:
- Difficulty breathing
- Abnormal heart rhythms
- Esophageal bleeding
- Perforation or tearing of the pharynx (throat) or esophagus
Average Hospital Stay
This is an outpatient procedure.
The throat may be sore for a few days following the procedure. To prevent inhaling food or drink into the lungs, you are asked not to eat or drink until the numbness in the back of the throat has subsided.
