What is the difference between tee and tte? As compared with TTE, TEE offers superior visualization of posterior cardiac structures because of close proximity of the esophagus to the posteromedial heart with lack of intervening lung and bone. This proximity permits use of high-frequency imaging transducers that afford superior spatial resolution.
What is the difference between tee and a transesophageal echocardiogram?
A transesophageal echocardiogram is done by inserting a probe with a transducer down the esophagus. This provides a clearer image of the heart because the sound waves do not have to pass through skin, muscle, or bone tissue. The TEE probe is much closer to the heart since the esophagus...
What is a TTE echocardiogram?
Echocardiograms: Transthoracic (TTE) & Transesophageal (TEE) What is an echocardiogram? An echocardiogram is one of the most common diagnostic tools cardiologists use to visualize the heart, aorta, and other blood vessels. An echocardiogram is essentially a Doppler ultrasound tool.
What is a tee test?
Quick facts. TEE is a test that uses sound waves to make pictures of your heart’s muscle and chambers, valves and outer lining (pericardium), as well as the blood vessels that connect to your heart.
What are the benefits of TTE and Tee?
Familiarity with TTE views provides an excellent knowledge base for recognition of the related TEE views. For instance, anatomical structures present in the TTE apical 4-chamber view are easily recognized in the TEE midesophageal 4-chamber view. TTE and TEE are complementary in their ability to provide better resolution of specific structures.
Is TEE the same as TTE?
As compared with TTE, TEE offers superior visualization of posterior cardiac structures because of close proximity of the esophagus to the posteromedial heart with lack of intervening lung and bone. This proximity permits use of high-frequency imaging transducers that afford superior spatial resolution.
Is TTE or TEE more accurate?
Recently, transesophageal echocardiography (TEE) has been proven superior to transthoracic echocardiography (TTE) for the detection of potential sources of cardiac embolism in patients with previous stroke. The diagnostic yield of TEE for the detection of a cardiac source of embolism is estimated between 40% and 60%.
What is the difference between transthoracic echocardiogram TTE and transesophageal echocardiogram TEE )?
The computer displays the echoes as images of the heart walls and valves. A traditional echocardiogram is done by putting the transducer on the surface of the chest. This is called a transthoracic echocardiogram. A transesophageal echocardiogram is done by inserting a probe with a transducer down the esophagus.
Which is more sensitive a TTE or a TEE?
TEE is more sensitive than TTE (which is quicker and noninvasive) for diagnosing and characterizing infective endocarditis, but even using TEE, results may be falsely negative before vegetations or other findings of endocarditis are detectable.
What can a TTE detect?
A transthoracic echocardiogram (TTE) is a test that uses ultrasound (sound waves) to create images of your heart. TTE can determine how well your heart is functioning and identify causes of cardiac-related symptoms.
When do you need a transesophageal echocardiogram?
A transesophageal echocardiogram (TEE) is a special type of echocardiogram. It is usually done when your doctor wants to look more closely at your heart to see if it could be producing blood clots. Like an echocardiogram, the TEE uses high-frequency sound waves (ultrasound) to examine the structures of the heart.
Why would a doctor order a transthoracic echocardiogram?
Getting a transthoracic echocardiogram, or TTE, gives your doctor a good view of your overall heart health including seeing how your heart beats and checking for any heart issues.
Why would a patient need a TEE?
Transesophageal echocardiography (TEE) is an ultrasound technology that provides highly detailed images of the heart and its internal structures. Our heart experts use TEE to detect blood clots, evaluate heart valves, and guide treatment for arrhythmias (abnormal heartbeats) and many other heart conditions.
How long does a TTE procedure take?
How long is the TTE? This test takes approximately 45 minutes to complete. What can I expect after my TTE?
Does TEE rule out endocarditis?
Discussion. Our results indicate that echocardiography, both TTE and TEE, has a low diagnostic yield in patients with a low clinical probability of endocarditis, who constitute the majority of patients in whom it is requested to “rule out” the condition.
What does TEE mean in medical terms?
Echocardiogram: Transesophageal (TEE) A transesophageal echocardiogram (TEE) is a type of echo test that uses sound waves to create pictures of your heart. Unlike other types of echo tests, a TEE creates pictures from inside your body. Your provider guides a thin, flexible tube down your esophagus.
What is infective endocarditis?
What is infective endocarditis? Infective endocarditis, also called bacterial endocarditis, is an infection caused by bacteria that enter the bloodstream and settle in the heart lining, a heart valve or a blood vessel. IE is uncommon, but people with some heart conditions have a greater risk of developing it.
Why would a doctor order a transthoracic echocardiogram?
Your doctor may suggest an echocardiogram to: Check for problems with the valves or chambers of your heart. Check if heart problems are the cause of symptoms such as shortness of breath or chest pain. Detect congenital heart defects before birth (fetal echocardiogram)
When should I TEE for endocarditis?
TEE for the diagnosis of endocarditis should be reserved only for patients who have prosthetic valves and in whom TTE is either technically inadequate or indicates an intermediate probability of endocarditis.
What 5 abnormalities can be found on the echocardiogram?
The echocardiogram can help detect:Abnormal heart valves.Congenital heart disease (abnormalities present at birth)Damage to the heart muscle from a heart attack.Heart murmurs.Inflammation ( pericarditis ) or fluid in the sac around the heart (pericardial effusion)More items...•

Trustee may be abbreviated either as Tte or Tee, and the designation of Trustee can appear either before or after a Trustee's name, so it's likely that there is no difference.
Loraine M. DiSalvo
Both abbreviations typically stand for trustee. It's possible that the convention in your document is to use one of them as the plural, "trustees."
Tanner Woods Pittman
Typically Trusts (and every other legal document) define terms that are reduced to abbreviations in the interests of brevity. You need to review the document itself,
What is ICE in medical terms?
Intracardiac echocardiogram (ICE): Intracardiac echocardiography represents a newer form of testing, with images taken inside your heart. We mostly use this approach to monitor treatments involving the placement of thin tubes called catheters inside your arteries.
What type of echocardiogram is most common?
We offer a full range of echo testing: Transthoracic echocardiogram (TTE): Transthoracic is the most common type of echocardiogram and is noninvasive, taking place entirely outside your body.
How to get a heart image with a transducer?
The technologist will place warmed gel on the chest and then place the transducer probe on the gel. You will feel a slight pressure as the technologist positions the transducer to get the desired image of the heart.
Why do doctors use echocardiograms?
An echocardiogram uses ultrasound, or harmless sound waves, to quickly and efficiently obtain valuable information about your heart. Our doctors regularly use an echocardiogram, or echo, when they have questions about the size, shape, and performance of your heart and its valves. Echocardiography is a versatile tool to help identify heart disease.
What is 3D echo?
3-D echo: Echocardiography typically shows a flat picture, but our machines can also create 3-D imaging. This technology is particularly helpful for identifying problems with heart valves, replacement heart valves, and the heart’s lower left chamber (left ventricle). We are studying new, additional ways to use 3-D echo.
Why do we need an echocardiogram?
Stress echocardiogram: We may need to run an echocardiogram as part of a comprehensive stress test that deliberately increases your heart rate and blood pressure. We take two sets of images, one at rest, and another after working out on a treadmill or stationary bike. If your health prevents such physical activity, we inject a medication that mimics the effect of exercise. This test is called a pharmacologic stress echocardiogram.
What is echocardiography?
Echocardiography is a versatile tool to help identify heart disease. We offer a full range of possible tests, including newer options that can provide 3-D imaging or fit inside the arteries. We use the type most suited to your heart and your needs.
What is a transthoracic echocardiogram?
During a transthoracic echocardiogram (TTE), a technician obtains views of the heart by moving a small instrument called a transducer to different locations on the chest or abdominal wall. A transducer, which resembles a microphone, sends sound waves into the chest and picks up echoes that reflect off different parts of the heart.
Are there any side effects?
There are no known risks from a TTE. However, during the test the technician may have to press hard on your chest with the transducer. Tell the technician if you feel any discomfort.
What is a TTE 2 chamber view?
A 2-chamber view in TTE may be obtained with the transducer in the apical position and the index pointed toward the patient’s head as demonstrated in composite Video 5 (see Supplemental Digital Content 5, http://links.lww.com/AA/A532 ). The inferior and anterior left ventricular walls, mitral leaflets, left atrium, and left atrial appendage are imaged in a 2-chamber view. In TEE, a 2-chamber view is obtained with the transducer in the midesophageal position and approximately 90° rotation. Figure 5 and composite Video 5 (see Supplemental Digital Content 5, http://links.lww.com/AA/A532) demonstrate these views. Due to its proximity to the esophagus, TEE in the midesophageal 2-chamber view is superior to TTE apical 2-chamber view in examination of the mitral leaflets and left atrial appendage for presence of thrombus. 7
What is a 4 chamber view in TTE?
A 4-chamber view in TTE may be obtained with the transducer in the apical position and the index pointed toward the floor as demonstrated in composite Video 4 (see Supplemental Digital Content 4, http://links.lww.com/AA/A531 ). Both atria, tricuspid valve, mitral valve, the right ventricular free wall, the inferoseptal and anterolateral left ventricular walls are visualized. In TEE, the corresponding view is obtained from the midesophageal acoustic window with transducer rotation at approximately 10°. During the intraoperative period, the midesophageal 4-chamber view is useful and complementary to the transgastric short-axis view to monitor biventricular filling and function. For both TTE and TEE, care must be taken to eliminate foreshortening that occurs when the ultrasound plane does not transect the left ventricular apex. Foreshortening may lead to erroneous left ventricular volume estimation and overestimation of left ventricular wall thickening. Color and spectral Doppler analysis of the mitral valve, tricuspid valve, and pulmonary veins, as well as tissue Doppler analysis of the mitral annulus are possible in these views. The midesophageal 4-chamber view offers superior axial and lateral resolution of the mitral valve leaflets owing to a higher frequency TEE transducer and its close proximity to the mitral valve. It is important to note that comprehensive imaging of the mitral valve and subvalvular apparatus requires multiple views and is beyond the scope of this paper. Figure 4 and composite Video 4 (see Supplemental Digital Content 4, http://links.lww.com/AA/A531) demonstrate TTE and TEE 4-chamber views.
What is the TEE view?
In TEE, the corresponding views may be obtained in the transgastric window with 0° rotation. TEE affords excellent wall motion and endocardial border visualization of the left ventricle in short axis. Adjusting anteflexion/retroflexion and/or probe advancement allow imaging of the basal, mid, and apical left ventricle in short axis. The TTE and TEE short-axis views are inverted with respect to one another. Therefore, the anterior wall of the left ventricle is at the top of the TTE image and the bottom of the TEE image.
What is the TTE view of the right ventricle?
The right ventricle, tricuspid valve, right ventricular outflow tract, pulmonic, and aortic valves can be evaluated by TTE in the parasternal short-axis view. With the transducer in the parasternal position and the index mark pointed toward the left shoulder, transducer tilt (the orientation of the transducer along a plane parallel to the ultrasound scan sector) is adjusted to demonstrate the aortic valve in short axis as demonstrated in composite Video 2 (see Supplemental Digital Content 2, http://links.lww.com/AA/A529 ). These structures may be imaged with TEE in the midesophageal right ventricular inflow–outflow view obtained at approximately 65° rotation. Color Doppler analysis of the tricuspid, pulmonic, and aortic valves is possible in these views. Figure 2 and composite Video 2 (see Supplemental Digital Content 2, http://links.lww.com/AA/A529) demonstrate these TTE and TEE views.
How many TTE views are there in Table 1?
In Table 1, 5 basic TTE views along with corresponding TEE views are listed with the structures that are imaged.
How long did a 62 year old man recover from a colectomy?
A 62-year-old man recovered for 1 hour in the post-anesthesia care unit following a colectomy. He became acutely hypotensive and hypoxic and did not respond to initial fluid bolus or epinephrine. He has a history of esophageal strictures and dysphagia, precluding the use of transesophageal echocardiography (TEE). A transthoracic echocardiogram (TTE) was performed to evaluate the cause of his hemodynamic instability.
What frequency is TTE?
TTE uses lower frequency (3-5 MHz) ultrasound to allow greater depth penetration at the expense of spatial resolution. The TTE transducer is placed directly on the patient’s chest in 4 windows: parasternal, apical, subcostal, and suprasternal. In contrast to TEE, TTE images anatomic structures from anterior to posterior.
What is a transesophageal echocardiogram?

What is a TEE?
Transesophageal echocardiography (TEE) is a test that produces pictures of your heart. TEE uses high-frequency sound waves (ultrasound) to make detailed pictures of your heart and the arteries that lead to and from it. Unlike a standard echocardiogram, the echo transducer that produces the sound waves for TEE is attached to a thin tube that passes through your mouth, down your throat and into your esophagus. Because the esophagus is so close to the upper chambers of the heart, very clear images of those heart structures and valves can be obtained.
What is a TEE test?
TEE is a test that uses sound waves to make pictures of your heart’s muscle and chambers, valves and outer lining (pericardium), as well as the blood vessels that connect to your heart.
How long before a tee test can you drink?
Check with your doctor. He or she may ask you not to have alcoholic drinks for a few days before the test, and not to eat or drink anything for at least 4 to 6 hours before TEE. Because you receive a sedative to help you stay calm, someone should drive you home after the test.
Why do we use a tee?
TEE is often used to provide information during surgery to repair heart valves, a tear in the aorta or congenital heart lesions. It’s also used during surgical treatment for endocarditis, a bacterial infection of the inner lining of the heart and valves.
Why do doctors use a tee?
Doctors use TEE to find problems in your heart’s structure and function. TEE can give clearer pictures of the upper chambers of the heart, and the valves between the upper and lower chambers of the heart, than standard echocardiograms. Doctors may also use TEE if you have a thick chest wall, are obese, have bandages on your chest, ...
What is an IV line?
A nurse puts an IV (intravenous line) in your arm, and gives you a mild sedative (medicine) to help you stay calm. The technician then places small metal disks (electrodes) on your chest. He or she attaches the electrodes by wires to a machine that will record your electrocardiogram (ECG) to track your heartbeat.
What is a transesophageal echocardiogram (TEE)?
A transesophageal echocardiogram (TEE) uses echocardiography to assess the structure and function of the heart. During the procedure, a transducer (like a microphone) sends out ultrasonic sound waves. When the transducer is placed at certain locations and angles, the ultrasonic sound waves move through the skin and other body tissues to the heart tissues, where the waves bounce or "echo" off of the heart structures. The transducer picks up the reflected waves and sends them to a computer. The computer displays the echoes as images of the heart walls and valves.
Why might I need a TEE?
Transesophageal echocardiography may be done to evaluate signs and symptoms that may suggest:
How do I get ready for a TEE?
Your healthcare provider will explain the procedure to you can ask questions.
What happens after a TEE?
You will be moved to a recovery area, where nurses will monitor your heart rate, ECG, blood pressure, and oxygen levels.
Why is the TEE probe closer to the heart?
This provides a clearer image of the heart because the sound waves do not have to pass through skin, muscle, or bone tissue. The TEE probe is much closer to the heart since the esophagus and heart are right next to each other.
How does a computer display echocardiograms?
The computer displays the echoes as images of the heart walls and valves. A traditional echocardiogram is done by putting the transducer on the surface of the chest. This is called a transthoracic echocardiogram. A transesophageal echocardiogram is done by inserting a probe with a transducer down the esophagus.
What is a TEE in heart?
Certain conditions of the heart are better seen with TEE, such as mitral valve disorders, blood clots or masses inside the heart, a tear of the lining of the aorta, and the structure and function of artificial heart valves. A TEE may use one or more of several special types of echocardiography, as listed below: M-mode echocardiography.
