Transoesophageal Echocardiogram (TOE)

What is an Transoesophageal Echocardiogram (TOE)?

A Transoesophageal Echocardiogram (TOE) is a specialised form of echocardiogram that provides detailed images of the heart. Unlike a standard transthoracic echocardiogram (TTE), which is performed on the chest wall, a TOE involves passing a specialised probe into the oesophagus (food pipe). The oesophagus sits directly behind the heart, allowing clearer and more detailed images.

The probe contains an ultrasound transducer that sends sound waves toward the heart. As the sound waves bounce off the heart structures, a computer converts them into images displayed on a screen. A TOE provides more detailed information than a TTE in certain situations, particularly when assessing heart valves, clots, infections, or structural abnormalities.

What to expect before your procedure

Please note this booklet provides general information about your procedure. The hospital booking team will contact you prior to your procedure with personalised instructions specific to your medical history.

Before

Your Cardiologist may request a blood test.

You may be asked to stop taking some medications.

You are required to fast for 6 hours prior to your procedure.

If you are a diabetic, please contact us for specific instructions.

Please pack an overnight bag should you be required to stay overnight for observation.

On the day of your procedure

Make transport arrangements to and from the hospital as you won’t be able to drive after the procedure.

Arrive at the Hospital at least two hours prior to your procedure.

During the procedure

The procedure is performed in a monitored hospital setting.

You will be given sedation (and sometimes a light general anaesthetic) to keep you comfortable.

Your throat may be numbed with a local anaesthetic spray.

The specialised ultrasound probe is gently guided into your oesophagus.

The probe transmits ultrasound waves to create detailed images of your heart.

Your breathing, blood pressure, and heart rhythm will be monitored throughout.

The procedure typically takes approximately 30 to 60 minutes.

Post procedure care & discharge information

A full report will be sent to your referring doctor regarding the results of your procedure.

You should not drive for the remainder of the day.

Avoid eating or drinking until the numbness in your throat has worn off (as advised by hospital staff).

Mild throat discomfort is common and usually settles within 24 hours.

If discharged on the same day, ensure someone is available to stay overnight with you.
