Problems are rare, but all procedures have some risk. The doctor will go over problems that could happen such as:

• Problems breathing
• Bleeding or damage to the mouth, throat, or esophagus

Things that may raise the risk of problems are:

• Throat problems
• Radiation therapy to the throat
• A history of stomach ulcers or esophageal varices
• A narrowed esophagus
• Sleep apnea or severe breathing problems such as chronic obstructive pulmonary disease (COPD)

Prior to Procedure

The doctor may talk to you about:

• Anesthesia options
• Any allergies you may have
• Current medicines, herbs, and supplements that you take and whether you need to stop taking them before the procedure
• Fasting before the procedure, such as avoiding food or drink after midnight the night before
• Whether you need a ride to and from the procedure

Anesthesia

You will be given medicine to make you sleepy. Throat spray will numb your throat.

Description of the Procedure

You will on your side lie on a table. Slippery material will be applied to a probe. The probe will be slid down the throat into the food pipe until it is near the heart. The probe will create images of the heart. When the imaging is done, the probe will be taken out.

How Long Will It Take?

15 to 30 minutes

Will It Hurt?

There may be some mild discomfort during the procedure. Your throat may be sore for a few days.

Post-procedure Care

Food and drink will need to be avoided until the throat numbness wears off.

The doctor will discuss the results of the test with you.
