Examination of Heart via Transesophageal Echo (TEE): Key Points on the Process
A transesophageal echocardiogram (TEE) is a minimally invasive diagnostic procedure used to assess the heart and surrounding structures. Here's what you need to know about the TEE procedure, its risks, and post-procedure care.
Preparation and Procedure
The TEE procedure typically takes 30-60 minutes, with most time spent on preparation. Before the procedure, you may be asked to fast for several hours. You will also receive a numbing spray in your throat to reduce discomfort during the insertion of the probe.
During the procedure, you will be lying on your left side with your head extended. The doctor will insert a flexible probe down your esophagus to produce detailed images of your heart. You may feel a sensation of gagging or mild discomfort, but these are normal.
Post-Procedure Care
After the TEE, you can expect a sore throat, but this should clear up within a few days. However, if the sore throat persists for more than a few days, seek medical attention. Other common post-TEE symptoms include difficulty swallowing, a hoarse voice, and nausea. These symptoms should disappear after a few hours.
Due to the use of numbing agents, hot liquids or foods should be avoided to prevent burns. Doctors also prohibit eating and drinking until the numbness from the throat spray wears off completely.
Sedation and Monitoring
A mild sedative may be administered to help you relax during the procedure. You may be in a "twilight" state of wakefulness after receiving the sedative, but you can still follow instructions for swallowing. After the procedure, a nurse will monitor you until you are fully awake and the sedative effect has worn off.
It is important to note that the sedative may increase the side effects of alcohol, so doctors recommend avoiding alcohol for a day or two after the TEE.
Risks and Complications
Serious complications of TEE are rare, but esophageal perforation is one potential complication. Other common complications and risks associated with TEE include throat and esophageal irritation or injury, upper gastrointestinal tract injury, discomfort and sedation-related effects, retching and gag reflex complications, and rare but serious complications like bleeding or arrhythmias.
Vigilance is warranted, and it is best to speak with a doctor about any concerns before or after the procedure. Although the overall adverse event rate is low compared to other invasive cardiac imaging techniques, careful patient selection and monitoring are crucial to ensure the safety and effectiveness of the TEE procedure.
In summary, TEE is generally a safe diagnostic procedure with common minor side effects like throat soreness and nausea. Serious complications such as esophageal injury or sedation risks are rare but possible, requiring careful patient selection and monitoring.
