Transoesophageal Echo (T.O.E.)
A Transoesophageal Echocardiogram (TOE) is a specialised heart ultrasound performed in hospital. It uses a probe passed gently down your oesophagus (food pipe) to capture high‑quality images of your heart. Because the probe is closer to the heart than in a standard echocardiogram, the pictures are much clearer and more detailed.
What happens during a Transoesophageal Echocardiogram?
- Hospital admission: This is usually a simple day procedure.
- Probe placement: A thin probe is passed down your oesophagus to take images of your heart.
- Sedation and comfort: Light sedation is given to help you relax, and a local anaesthetic is used to make passing the probe easier.
- High‑quality images: The test provides detailed pictures of your heart’s structure and function.
- Time required: The procedure, including recovery, takes about 3–4 hours.
