Transoesophageal echocardiogram

Transoesophageal echocardiogram (also known as TOE or TEE) is a type of echocardiography that provides detailed images of the heart and its structures. This procedure is performed by inserting a probe with a transducer at its tip into the patient's oesophagus.

Procedure

The procedure begins with the patient being given a local anaesthetic to numb the throat. A sedative may also be administered to help the patient relax. The probe is then gently inserted into the oesophagus. The transducer at the tip of the probe emits sound waves that bounce off the heart and return to the transducer, creating images of the heart on a monitor.

Uses

A transoesophageal echocardiogram is used when a transthoracic echocardiogram (TTE) does not provide sufficient information. It can provide detailed images of the heart's structures, including the atria, ventricles, valves, and aorta. It can also detect blood clots and infections in the heart, assess damage after a heart attack, and evaluate the effectiveness of heart surgery or other treatments.

Risks

While a TOE is generally safe, there are some risks associated with the procedure. These include minor throat discomfort, bleeding, and rare complications such as oesophageal perforation or arrhythmia.
