Transesophageal Echocardiogram
About the Test
The Transesophageal Echocardiogram or TEE is performed when a regular echocardiogram will not produce the best picture of the heart. TEEs are ordered for these patients and patients with abnormalities of the chest, lungs and rib cage that may block the view of the heart. In these cases a small scope or probe is inserted through the esophagus. To minimize discomfort associated with the insertion of the probe, patients are mildly sedated with intravenous medicine and oral novocaine-like sprays. The esophagus lies close to the heart, so excellent views may be obtained. TEEs help to evaluate:
- A heart difficult to examine using conventional echocardiography
- Patients with congenital heart disease
- Patients with replaced heart valves
- Patients suspected of having strokes
At Danbury Hospital, a physician and nurse experienced in the procedure performs the TEE.
Preparation
- Do not eat or drink anything for at least 6 hours prior to the exam.
- Medications may be taken with a small sip of water at the normally scheduled time.
- Since intravenous sedation is used, you must have a person drive you home afterwards.
- Tell the doctor if you have a problem swallowing or if you have any conditions involving your esophagus or stomach.
- If you wear dentures or oral prostheses, you will need to remove them.
What Happens During the Test
You will change into a hospital gown and be taken to the procedure room. You will be asked to lie on your left side. Your throat is sprayed with an anesthetic to numb it. You may be given a low dose of a sedative through the IV line in your arm to help you relax. The doctor gently inserts the probe into your mouth. As you swallow, the tube is slowly directed into the esophagus. You may gag when the probe first enters the esophagus, and you may feel the probe moving, but the procedure is generally not painful.
The transducer is positioned in the esophagus just behind the heart, where high quality images are recorded. With the help of control knobs, the doctor can move the tip of the probe up, down and sideways. This makes it possible to view various parts of the heart from different angles. Your heart rate, blood pressure, and oxygen level are carefully monitored throughout the test. Suction may be needed to clear secretions from your mouth. You may also be given oxygen.
Length of Test
The test usually takes between 15 and 20 minutes. Allow two hours from arrival to the time you can leave.
After Your TEE
- Arrange for someone to drive your home. Don't drive for 8 hours
- Do not drink for 2 hours or as instructed after the exam.
- If your throat is slightly sore after the test, take cold drinks and lozenges to soothe it.
- Be sure to report unusual symptoms such as difficulty in swallowing, shortness of breath, chest pain, bleeding or fever.
