Quick summary
Transesophageal echocardiography, or TEE, is a heart imaging test that uses an ultrasound probe placed in the esophagus to create detailed images of the heart. It is often used when a standard echocardiogram does not give a clear enough view.
Medical disclaimer: This article is for general information only and does not replace advice from a qualified healthcare professional. If you have questions about a TEE, your medical team or the official patient leaflet can explain how the test applies to your situation.
What is transesophageal echocardiography?
Transesophageal echocardiography (TEE) is a type of echocardiogram that uses sound waves to create moving images of the heart. The probe is placed in the esophagus, which sits close to the heart, allowing for detailed views of heart structures.
Because the probe is closer to the heart than in a standard chest echocardiogram, TEE can provide clearer images in some situations. It is often used when doctors need a closer look at the heart’s valves, chambers, or nearby blood vessels.
Medical definition of TEE
In medical terms, TEE means transesophageal echocardiography. It is a diagnostic imaging test that helps clinicians assess the heart using ultrasound from inside the esophagus rather than from the chest wall.
This approach can be helpful when ordinary echocardiography does not show enough detail. The test may support evaluation of heart valve problems, blood clots, and other structural concerns mentioned in the original content.
Why do people need TEE?
A doctor may recommend TEE when more detailed heart images are needed. It is commonly used to assess the heart valves and to look for possible sources of emboli, such as blood clots in the heart.
TEE may also be used when a person has symptoms such as arrhythmias or unexplained chest pain, or when a clinician needs to monitor a known heart condition more closely.
In some people, standard echocardiography may not provide clear enough images, including those with obesity or lung disease. In those cases, TEE can offer a better view of the heart.
What can TEE help doctors look at?
TEE can help doctors examine several parts of the heart in more detail, including:
- Heart valves
- Heart chambers
- Possible blood clots
- Some aortic abnormalities, such as aneurysms
The exact reason for the test depends on the person’s symptoms and medical history.
What are the risks of TEE?
TEE is generally considered safe, but it does have some risks. The most common issue is temporary throat discomfort from the probe.
Other possible risks mentioned in the original content include a reaction to sedative medicine, nausea, bleeding, perforation of the esophagus, or aspiration. Serious complications are uncommon, but they can happen.
If you are scheduled for TEE, your healthcare team can explain the risks that matter most in your case.
How do I prepare for TEE?
Preparation helps reduce risk and improve the quality of the test. People are often told not to eat or drink for 6 to 8 hours before the procedure.
You may also be asked to discuss your current medicines, allergies, and any past surgery or medical problems with the healthcare team. In some cases, medicines that affect blood clotting may be reviewed before the test, but you should follow the instructions given by your clinician.
If you are unsure about any preparation step, check the appointment instructions or ask the clinic before the procedure.
What happens during TEE?
TEE is usually done with sedation to help you stay comfortable. A local anesthetic may also be used to numb the throat.
The probe is then gently passed into the esophagus so the clinician can obtain images of the heart from different angles. The test often takes about 30 to 60 minutes.
During the procedure, the medical team monitors your vital signs and comfort. The images are reviewed by the clinician, and results are discussed after the exam or at a follow-up visit.
What happens after TEE?
After the test, you are usually monitored until the sedative wears off. Temporary throat numbness or soreness is common and often improves within a few hours.
You are typically advised not to eat or drink until your throat sensation returns, to reduce the risk of choking or aspiration.
A follow-up appointment may be arranged to review the findings and discuss next steps if needed.
What should I watch for after TEE?
Contact your healthcare provider if you develop symptoms such as difficulty breathing, chest pain, significant throat discomfort, fever, excessive bleeding, or trouble swallowing after the procedure.
These symptoms are not expected for most people and may need prompt medical attention.

Frequently asked questions about TEE
▸ What is TEE in medical terms?
TEE stands for transesophageal echocardiography. It is a diagnostic ultrasound test that uses a probe in the esophagus to create detailed images of the heart.
▸ Are you awake during a transesophageal echocardiogram?
Many people receive sedation during TEE, so they are relaxed and may be only partly aware of the procedure. The exact level of awareness can vary.
▸ Why would someone need a TEE?
A doctor may order TEE to get a closer look at the heart valves, chambers, blood clots, or other structures when more detail is needed than a standard echocardiogram can provide.
▸ How long does a TEE usually take?
The original content states that the procedure usually takes about 30 to 60 minutes, although the total visit may be longer because of preparation and recovery time.
▸ What should I do if my throat feels sore afterward?
Temporary throat discomfort can happen after TEE. If the soreness is severe, lasts longer than expected, or comes with trouble swallowing or breathing, contact your healthcare provider.
Safety reminder
Before a TEE, follow the instructions given by your healthcare team, especially about fasting and medicines. After the test, do not eat or drink until you have been told it is safe to do so. Seek medical help promptly if you develop concerning symptoms after the procedure.
Key takeaways
TEE is a specialized heart imaging test that can provide detailed views when standard echocardiography is not enough. It is used for assessment of heart valves, blood clots, and other heart-related concerns, and it usually involves sedation and short-term recovery monitoring.
