Transesophageal echocardiogram (TEE)

           For this test, the probe is passed down the esophagus instead of being moved over the outside of the chest wall. TEE shows clearer pictures of the heart, because the probe is located closer to the heart and because the lungs and bones of the chest wall do not block the sound waves produced by the probe.
 

 How is it done?

 
  • Before the test, medicine to decrease saliva and stomach secretions and sedative to relax the patient. The throat may be numbed with an anesthetic spray to ease insertion of the probe.
  • The test takes about 2 hours. The probe will be in place in your esophagus for about 10 to 20 minutes

  Pre-procedure preparation

 
  • Do not eat or drink for at least 6 hours before the TEE.
  • If the patient has dentures or dental prostheses, they may need to be removed before the test.
  • If you have medical problems involving the throat, esophagus, or stomach, tell your doctor before getting this test.
  • Before a TEE, you will be given a sedative. You will not be able to drive for at least 12 hours after the procedure. Be sure to make arrangements in advance for someone to pick you up after the test.

  Risks

 
  • Nausea.
  • Mouth and throat discomfort.
  • Minor bleeding.
  • Trouble breathing.

  • Insertion of the probe may cause esophageal damage. This is rare.
