CaRi-heart technology
Revolutionary new technology to assess the risk of a serious heart condition or heart attack – many years before anything happens.
A transoesophageal echocardiogram (TOE) is a specialised procedure that uses echocardiography (ultrasound) to scan your heart and assess its function.
If you have symptoms or concerns about the health of your heart, we can offer you rapid access to a TOE procedure and other cardiac tests at one of our facilities in London and Birmingham.
You might need a transoesophageal echocardiogram if you're experiencing any of the following symptoms and other tests have suggested a need for more detailed imaging of your heart:
Don't hesitate to book an appointment with a cardiologist if you experience any of these symptoms, especially if they're persistent or gradually worsening. They could indicate a broad range of conditions, some of which could be life-threatening.
We can confirm your appointment within 24 hours. Your cardiac consultant will recommend a TOE scan and any other tests needed to give you a diagnosis. You can undergo the diagnostic procedures on the same day as your appointment, and your results will be available within two working days. After this, your consultant will explain your results to you and, if further action is necessary, recommend the most effective way to move forward – whether that's more advanced testing, physiotherapy or surgical treatment.
A transoesophageal echocardiogram (TOE) is a specialised ultrasound scan that produces detailed images of your heart that move in real-time. Unlike other types of echocardiograms, a TOE procedure takes images from your gullet (oesophagus) inside your body, instead of from outside, resulting in more detailed pictures. Our cardiovascular experts can use these images to provide a more detailed diagnosis and work out an effective course of treatment.
During a transoesophageal echocardiogram, an ultrasound sensor is passed into your gullet (oesophagus) through your mouth and throat. The sensor emits ultrasonic waves that pass through soft tissues to reach your heart, where they echo or reflect off the heart's different structures.
The sensor picks up the reflected waves and sends them to a computer, which displays moving, real-time images of your heart. This helps diagnose any problems with your heart function, structure or valves.
The most common type of echocardiogram is called a transthoracic echocardiogram (TTE). This procedure involves placing an ultrasound sensor on the surface of your chest. The ultrasonic waves must travel through skin, muscle, bone and soft tissues before they reach your heart.
With a transoesophageal echocardiogram, the ultrasound probe is inserted into your gullet via your mouth and throat. The gullet is located directly behind the heart, so the ultrasound waves are closer to the heart and must only travel through soft tissues to reach it. As a result, TOE procedures produce clearer images of the heart compared to the TTE approach.
There are several reasons why your consultant might recommend you have a TOE scan, including but not limited to:
Our cardiac diagnostic is the most comprehensive in the UK, delivering more than 20,000 echocardiograms each year across the country. Our specialists will ensure you get the most effective diagnostic procedure for you, whether that's a TOE scan or another type of heart test.
A transoesophageal echocardiogram can help diagnose signs and symptoms of many different conditions including:
Your consultant will explain the procedure to you, answer any questions you have and tell you how to prepare. You'll need to stop eating and drinking for a few hours beforehand.
It's also important you let your consultant know if you're taking any medication, as you may need to stop taking it before your scan. Depending on your medical history, they may have other specific recommendations for how you should prepare.
A TOE scan usually takes about 20 minutes in the catheter lab.
First, your medical team will ask you to remove any dentures, jewellery or other objects that might interfere with the procedure. They may also ask you to empty your bladder and change into a hospital gown.
Next, the medical team will offer you general anaesthetic or a sedative to help you feel as comfortable as possible during the procedure. They'll also spray the back of your throat with anaesthetic to numb the area.
When you're ready, you'll be asked to lie on your side and wear a bite protector. You'll be connected to an electrocardiogram (ECG), which will monitor your vital signs such as heart rate, blood pressure, breathing rate and oxygen level during the TOE procedure. The lights may be dimmed to help the team see the images better.
Your consultant will then pass a flexible tube (the ultrasound sensor) through your mouth and into position. The sensor takes real-time images of your heart valves and chambers, which show up on a screen for your consultant to analyse. The team will carefully remove the sensor after they've taken all the images they need.
Ultrasound waves are harmless and carry no exposure risks, unlike X-rays. The main risks of a transoesophageal echocardiogram come from the insertion of the probe into the gullet.
Some people have a sore throat after the procedure, lasting from a few hours to as much as a few days. Other risks are rare but could include:
There may be other risks depending on your personal medical history. Your consultant will evaluate you carefully before recommending a TOE scan or any other medical procedure. They'll also explain all the risks involved and answer any questions you have.
When the TOE procedure is over, the medical team will move you to a recovery area where nurses will continue to monitor your vitals. You'll be able to get dressed when they're satisfied that you're stable. Your consultant will then discuss your results with you and let you know if you need further testing or treatment.
You should be able to go home on the same day as your scan. Please arrange for someone to travel home with you, as you won't be able to drive for the first 24 hours due to the sedatives or anaesthetic. Make sure you get plenty of rest during this time.
Your consultant will let you know when you can get back to your usual routine and activities. They'll also give you advice on when you can resume your usual medication, exercise, travel, diet and alcohol consumption.
As well as transoesophageal echocardiograms, there are other types of echocardiographic procedures that help your consultant better understand your heart in different ways. These include:
Your consultant will recommend the most suitable diagnostic tests given your symptoms and medical history.
The HCA UK network includes several outpatient clinics that can provide you with unparalleled cardiac procedures such as transoesophageal echocardiograms on an outpatient basis. Our friendly cardiac physiology team will welcome you and make you feel comfortable, talking you through the details of whatever tests you need so you have peace of mind. We can offer you several cardiac tests, the most common being:
A test to measure and record heart activity. An ECG is a simple and non-invasive test to assess heart rate and rhythm and diagnose or monitor heart conditions.
A stress test or exercise tolerance test gives information about how your heart functions under the strain of exercise
CT coronary angiogram with calcium scoring. A cardiac CT scan offers a non-invasive technique to evaluate the heart arteries and structure of the heart using X-rays.
