Transesophageal echocardiography (TEE) is a procedure that allows imaging of the heart. It uses ultrasound to produce moving images of the inside of the heart and arteries in real time.
TEE is usually performed when a clear image of the heart cannot be obtained by conventional echocardiography and to analyze in greater detail some cardiac structures (valves, atrial appendage, congenital defects).
Transesophageal Echocardiography
uses high frequency sound waves
What does it consist of?
To perform transesophageal echocardiography, the throat will be sprayed with a local anesthetic spray to numb it. An intravenous line is then placed in the arm, through which a sedative will be administered to relax the patient during the test.
The specialist will place electrodes on the chest, which will be connected through wires to an electrocardiograph to monitor the heart rhythm during the study. The probe (a thin, flexible tube) is then introduced through the mouth and throat until it reaches the esophagus. The transducer, which is located at the end of the probe, will obtain the images of the heart and the specialist during the process can move the probe to visualize the structures of the heart from different angles.
When the necessary images of the heart have been obtained, the probe will be withdrawn intravenously and disconnected from the electrocardiograph.
Why is it performed?
The test is used to accurately diagnose heart problems. That is, it can detect problems with the heart valves, inflammation or tears in the aorta, clots (thrombi) inside the heart, infections in the heart valves and damage to the heart muscle.
In addition, it allows to know how the heart works, as well as its size, and analyzes the flows through the interior of the heart.
Preparation for transesophageal echocardiography (TEE)
Do not eat or drink anything for at least 4-6 hours before transesophageal echocardiography. You should consult with the specialist about the medications you usually take, depending on the case you may be asked to stop taking them before the test.
How do you feel during the test?
The most uncomfortable part of the study is the introduction of the probe down the throat, it is common to gag, as well as a slight discomfort. However, when the probe is in place, you will not feel any pain.
You may have a sore throat or difficulty swallowing after the test. These symptoms tend to go away within a few days.
What abnormal results mean
Your specialist should review the transesophageal echocardiogram images to identify if there are any problems with your heart, heart valves, or blood flows.
This test complements other cardiac studies. In some cases it is also used during catheter-based interventions on the heart, such as valve implants or certain devices used to close defects inside the heart.
