A "heart scope," referring to a procedure involving a scope to view the heart, is most commonly known as a transesophageal echocardiogram (TEE).
Transesophageal Echocardiogram (TEE) Explained
A transesophageal echocardiogram (TEE) is a type of echocardiogram that uses a probe inserted down the esophagus (the tube connecting your mouth to your stomach) to get a clearer picture of your heart. Because the esophagus sits directly behind the heart, using a probe in this location provides more detailed images than a standard echocardiogram, which is performed on the chest wall.
Why is a TEE Performed?
TEE is used when a standard echocardiogram doesn't provide enough information. Some reasons a doctor might order a TEE include:
- Evaluating valve function: TEE can help identify problems with the heart valves, such as stenosis (narrowing) or regurgitation (leaking).
- Detecting blood clots: TEE can help visualize blood clots in the heart, particularly in the left atrium.
- Assessing the aorta: TEE can provide a clear view of the aorta, the large artery that carries blood from the heart to the rest of the body.
- Investigating the source of a stroke: If someone has had a stroke, TEE can help determine if a blood clot from the heart was the cause.
- Monitoring during surgery: TEE can be used during heart surgery to help guide the surgeon and assess the results.
What to Expect During a TEE
During a TEE, you will typically be given medication to help you relax. The doctor will numb your throat with a spray, and then gently insert the probe into your esophagus. Images of your heart are then captured using ultrasound technology. The procedure usually takes about 15-30 minutes.
Alternatives to TEE
While TEE offers a detailed view of the heart, other methods are available for visualizing the heart, including:
- Transthoracic Echocardiogram (TTE): The standard echocardiogram performed on the chest wall.
- Cardiac MRI: Uses magnetic fields and radio waves to create detailed images of the heart.
- Cardiac CT Scan: Uses X-rays to create detailed images of the heart.
The choice of imaging method depends on the specific clinical situation and the information needed.
