Happy Monday! Today's Medical Monday is about transesophageal echocardiography (TEE).
What is a TEE?
A TEE is a diagnostic test that uses sound waves to create detailed images of the heart from within the esophagus. During this procedure, a small ultrasound probe is advanced through the patient's throat into the esophagus. This is done because the esophagus lies behind the heart. A TEE allows the ultrasound to bypass the rib cage and lungs, therefore an unobstructed image is created. Usually, physicians order a TEE in suspected valve or aortic disease cases.
Why is TEE important in aortic disease?
Visualization: A TEE provides unobstructed images of the aortic arch and descending thoracic aorta.
Detection: A TEE is especially useful in the detection of aortic dissection. Physicians can see blood flow and tear location by using this diagnostic test.
Assessment Pre and Post Surgery: A TEE is used before and during surgical operation. Preoperatively, it's used to understand the unique structure of the patient's aorta. Intraoperatively, it allows for quick real-time imaging to assess surgical treatment's success.
Valve Function Evaluation: A TEE can be used to assess function in cases of suspected aortic valve dysfunction caused by aortic disease.
Monitoring: A TEE can be used during aortic stent procedures to ensure proper positioning or adjustment of the stent. Its ability to provide real-time imaging is very useful during this procedure.
Here's a TEE image of ascending aortic dissection.
Are there any risks?
The risk of serious problems is low even though a TEE is considered an invasive procedure. TEE only requires local anesthesia which consists of a numbing/pain relieving spray applied to the back of the throat. Additionally, medication is given through IV for relaxation. Some patients have a sore throat after a TEE, but this usually resolves within a few days or even hours. Although very unlikely, complications such as allergic reactions, aspiration pneumonia, arrhythmias, or minor esophageal bleeding can occur. Always remember to talk to your doctor about any risks or concerns.
That wraps up this week's Medical Monday! Make sure to join us again in 2 weeks for the next Medical Monday blog post. Have a great weekend, and Think Aorta.
