Transesophageal Echocardiography or TEE is a diagnostic test used to create detailed images of the heart and the surrounding blood vessels. The technology uses high-frequency sound waves and produces images just like an ECG. However, in TEE, the ultrasound probe is passed down your throat instead of attaching to the chest so that it can produce more accurate images.
Why Is A TEE Needed?
A TEE is usually advised when the cardiologist notices an abnormality in an EGC. Through TEE, he can better locate and evaluate the condition and can devise a customized treatment plan. The followings are the conditions/symptoms that warrant TEE:
- Arrhythmia
- Heart valve conditions like stenosis or regurgitation
- Endocarditis (heart infection)
- Presence of masses in the heart
- Congenital heart diseases, such as atrial septal defect or patent ductus arteriosus.
TEEs are also used during surgeries to monitor the condition of the heart in real time.
How Is A TEE Done?
- To reduce the risk of complications, a certain period of fasting is usually recommended before TEE.
- Before the procedure, a mild sedative will make sure that you do not feel any pain or discomfort. However, some pressure can be expected.
- You will lie on your left side as the procedure begins.
- The technician will pass a small and flexible probe with a camera and ultrasound transducer through your mouth and into your esophagus. You can assist the process by ‘swallowing’ it.
- Once the probe is in place, it will move around taking pictures of the heart and blood vessels and recording them. To assist the process, breathe or hold it as directed by the technician.
- The entire process can go on for 30-45 minutes. And then the probe will be guided out of your system gently and carefully.
- Post TEE, you will be monitored for a while to see if you recover well.
- Soreness in the throat is normal and can last between a few hours to a day. For this, you will receive some medication to soothe your discomfort.
- The images will be sent to your cardiologist and you can consult him to understand your treatment options.
