There are several reasons why a person might have a transesophageal echocardiogram and these include: (1) to evaluate whether or not a person have an infection of one the heart valves (endocarditis); (2) to evaluate whether or not a person has a small blood clot in the heart; (3) to evaluate whether or not a person has a small hole that allows blood to pass between the two upper or the two lower chambers of the heart; and (4) to evaluate whether or not a person has a split or tear between the layers of the walls of the aorta (aortic dissection)

There is very little preparation for this procedure. You will likely be asked not to eat or drink for 8 to 12 hours prior to the procedure. Also, you will need to arrange to have someone drive you home after the procedure.

Prior to the beginning of the procedure, you will be given a sedative which will make you feel relaxed and drowsy. However, you will still be able to be awoken if necessary. Then, the nurse will spray the back of your throat with an anesthetic solution to depress your gag reflex. Then, the tube will be passed down your esophagus and the procedure will be performed.

Complications from this procedure are extremely rare and there is very little risk involved. The two main complications are: (1) slightly sore throat after the procedure and (2) small tear in the esophagus when the probe is swallowed which may heal by itself or require stitches.

Due to the fact that you will be given a sedative, you will be required to have someone else drive you home. You will likely be very drowsy after the procedure. You can return to your normal activities on the next day.

You should call your cardiologist immediately and/or return to the emergency department immediately if you begin coughing or vomiting up blood after the procedure.

You should follow all the instructions that your healthcare provider gives you.
