A transoesophageal echocardiogram is a test used to assess the heart’s structure and function. Similar to a small microphone, a transducer emits high-powered ultrasound waves that penetrate the skin, bodily tissues and heart muscle. As a result, the sound waves bounce against the structures to create images of the heart and surrounding tissue. The reflected waves from the transducer are transferred to a computer and converted to images of the heart valves and walls.

A transoesophageal echocardiogram is much more invasive than a transthoracic echocardiogram because Dr Hassen inserts a probe down the oesophagus.

How do you perform the Echo procedure?

The patient is instructed to lie on their side with a wedge in place to support the back. Then, an electrocardiogram monitor is connected with sticky electrodes to record the heart. Next, Dr Hassen sprays a mild anaesthetic at the back of the throat so you do not feel discomfort when passing the ultrasound probe down the throat. Furthermore, he places a bite protector in the mouth to prevent the patient from biting their tongue.

Throughout the procedure, oxygen is fed through the nasal tubes. Also, your heart rate, blood pressure and oxygen levels are monitored.

By swallowing when asked, you can help the probe move down more smoothly. Once the probe rests in the correct place, it will be able to capture images. After this, when Dr Hassen is content with the images taken, he can gently remove the probe from the throat.

You can return home once the gag reflex returns and your vital signs remain stable. However, you may need someone to drive you home because you will feel tired for the rest of the day after the echocardiogram. Usually, the procedure is carried out on an outpatient basis, so you may return home on the day unless Dr Hassen determines your condition needs further observation overnight in the hospital.
