A transoesophageal echocardiogram is an ultrasound of the heart performed under general anaesthetic where a flexible ultrasound probe is placed down your oesophagus (throat).

A ToE is used to help assess problems with a heart valve or structural heart defects not seen clearly with a regular echocardiogram.

A cardioversion is a controlled electric shock to treat abnormal heart rhythms such as atrial fibrillation. A ToE is performed first to check that there is no blood clot in any of your heart chambers. These are day-only procedures.
