This information will help you prepare for your transesophageal echocardiogram (TEE) at Memorial Sloan Kettering Cancer Center (MSK).
A transesophageal echocardiogram (TEE) is a procedure that uses ultrasound (sound waves) to create moving pictures of your heart. Your doctor will insert a probe (flexible tube) into your esophagus. This will allow your doctor to get detailed pictures of your heart because your esophagus is directly behind your heart.
A TEE lets your doctor know how your:
- Heart valves are working
- Heart muscle is moving
- Blood is flowing

Get a letter from your doctor, if necessary
If you have an automatic implantable cardioverter-defibrillator (AICD), you will need to get a clearance letter from your cardiologist before your procedure.

Where to go
Please arrive at the Endoscopy Suite at 1275 York Avenue. This is the main building of MSK. Take the M elevator to the 2nd floor.
What to expect
Once you arrive at the hospital, doctors, nurses, and other staff members will ask you to state and spell your name and date of birth many times. This is for your safety. Patients with the same or similar names may be having procedures on the same day.
After changing into a hospital gown, you will meet your nurse. He or she will place an intravenous (IV) catheter into a vein, usually in your hand or arm. At first you will receive fluids through the IV, but it will be used later to give you anesthesia (medication to make you sleepy). Your doctor will explain the procedure, and answer any questions you have. Tell your doctor if you:
- Are not able to swallow liquids or food
- Have had surgery to your esophagus or radiation to your chest, spine, or upper back
- Are allergic to any medications
When it's time for your procedure, you will be brought into the procedure room and helped onto an exam table. You will be attached to equipment to monitor your heart, breathing, and blood pressure. You will also receive oxygen through your nose, and a mouth guard will be placed over your teeth to protect them. If you wear dentures, you will be asked to remove them. Your doctor may numb your throat with a spray. You will receive anesthesia through your IV, which will make you fall asleep.
Once you are asleep, your doctor will insert the probe (flexible tube) into your mouth and pass it slowly down your esophagus. Your doctor will move it around slightly to take pictures of your heart and blood flow. This takes about 15 minutes.
After Your Procedure
In the recovery room
You will wake up in the recovery room. Your nurse will continue to monitor your heart, breathing, and blood pressure. Once you are fully awake, your nurse will remove your IV. If you have someone waiting with you, your nurse will explain your discharge instructions to both of you before you go home.
