A transesophageal echocardiogram (TEE) is a diagnostic procedure that uses ultrasound to obtain detailed images of the heart. This article explains what to expect during a TEE, including the level of awareness and preparation.
Understanding Your Transesophageal Echocardiogram
A transesophageal echocardiogram (TEE) is a specialized ultrasound that creates moving pictures of the heart. Unlike a standard echocardiogram, a TEE guides a thin, flexible tube with a tiny camera and ultrasound transducer down the esophagus. This allows for clearer images because the esophagus lies directly behind the heart, avoiding interference from ribs or lungs. TEE provides detailed views of the heart’s structure and function, helping identify conditions like blood clots, evaluate heart valve function, diagnose defects, and assess heart size or wall thickness.
Ensuring Comfort During the Procedure
Patients undergoing a transesophageal echocardiogram are not fully awake, nor are they under general anesthesia. They usually receive conscious sedation, which allows them to remain drowsy and relaxed. Patients can often respond to verbal cues but may have little to no memory of the procedure. Conscious sedation is preferred due to its quicker recovery time compared to general anesthesia. To enhance comfort, a local anesthetic spray numbs the throat to minimize the gag reflex before tube insertion. Throughout the TEE, healthcare professionals monitor the patient’s heart rate, blood pressure, oxygen levels, and breathing to ensure safety and allow for immediate adjustments.
Preparing For and Recovering From Your TEE
Before a TEE, patients fast for six to eight hours to ensure an empty stomach and reduce aspiration risk. Patients should discuss all current medications, including over-the-counter drugs and supplements, with their doctor, as some may need adjustment.
Following the TEE, patients are moved to a recovery area where vital signs are monitored until sedation wears off. A mild sore throat, hoarseness, or difficulty swallowing is common for a few hours to a few days. Do not eat or drink until throat numbness subsides to prevent choking.
Due to sedation, arrange for someone to drive you home, and avoid driving, operating machinery, or making important decisions for the rest of the day. Contact a healthcare provider immediately for persistent severe throat pain, difficulty breathing, chest pain, or significant bleeding.
