Transthoracic Echocardiogram

What is an echocardiogram?

An echocardiogram or "echo" is an ultrasound of your heart. A transthoracic echocardiogram is an echo that is performed by an ultrasound probe on the chest wall (thoracic). It may also be called a resting echocardiogram or echo, TTE or cardiac ultrasound.

An echocardiogram assesses the structure and function of your heart. It uses ultrasound waves to create moving images of your heart as well as assessing the flow of blood through the heart valves and chambers.

An echocardiogram is different to an electrocardiogram (ECG) which assesses the electrical activity off your heart.

Other common types of echocardiogram in Cardiology include:

Exercise stress echocardiogram - echo images obtained before and after exercise
Dobutamine stress echocardiogram - echo images obtained during a Dobutamine infusion (Pharmacological equivalent exercise stress echocardiogram)
Transoesophageal echocardiogram - echo images obtained from an ultrasound probe inserted into the oesophagus under sedation

Why do I need an echocardiogram?

An echocardiogram is a routine cardiology investigation.

It assesses:

how your heart muscle is pumping
the size of your heart
the heart muscle thickness
how the valves in your heart are working
looks for fluid around the heart
assesses the major blood vessel coming from the heart - the aorta
assess the pressures in the blood vessels in the lungs
assesses for "hole in the heart"

Is there any preparation required?

No preparation is required for a transthoracic echocardiogram. Take your usual medications as normal. Eat and drink normally, no fasting is required.

Are there any risks associated with the test?

There are no harmful effects from an echocardiogram. There is no radiation from ultrasound studies.

You may experience minor discomfort from the ultrasound probe being pressed against the chest wall, more so if you have chest wall tenderness. The reason for the pressure on the ultrasound probe is to ensure good image quality. During an echocardiogram three "sticky" ECG (electrocardiogram) dots are placed on the chest. The ECG is required to match the cardiac cycle with the cardiac images. Occasionally patients experience skin irritation from the ECG dots. Applying a gentle moisturiser can help the irritation.

How long will it take?

Appointments for echocardiograms are 45 minutes long. The echocardiogram images may take 30-45 minutes. Occasionally the echocardiogram study may require additional images and take longer than the scheduled 45 minutes.

When do I get the results?

Following the echocardiogram, the images are reviewed by a Cardiologist and then a formal report is sent to the doctor who referred you for the echocardiogram. Let us know at the time of your appointment if there is another doctor involved in your care who you would like a copy of the report sent to.

What can I expect at the echocardiogram appointment?

How much does an echo cost?

Following a referral to our practice for an echocardiogram, you will be contacted by our amazing medical receptionist and booked for an appointment. Prior to the appointment we ask you to fill out a patient registration form if you have not been to our practice before. We also have a consent form for you to sign prior to the echocardiogram. If you have any results of previous echocardiograms (or upload here), please bring them with you to your appointment and we can import them into your patient file for comparison. If you have had a previous echocardiogram and do not have a copy of the report, we will ask to sign a consent to request a copy for our records.

After checking in at the reception desk, we ask you to take a seat in the waiting room. When the sonographer is ready for your appointment they will call you in to the testing room.

You will be asked to undress to the waist. You will be provided with a gown that allows access to the chest for scanning. Please let us know if you have any concerns about removing clothing or under-garments.

When ready you will be asked to lie on your back on the scanning bed. Three "sticky" ECG dots will be placed on your chest to record the electrocardiogram (ECG).

The lights in the testing room will be dimmed to allow the sonographer to see your images more clearly. You will be asked to lie on your left-hand side, with you left arm up beside your head and your right arm down along your side with your hand placed on your hip. Please let the sonographer know if there are any concerns with lying on you left hand side or other concerns you may have.

Ultrasound gel (can be cold, water-based) is placed on the probe prior to placing the probe on your chest. The gel helps the transmission of the ultrasound waves.

You may be asked to hold your breath, either hold your breath in or hold your breath out. This is to minimise movement during an image acquisition and also for some views it is required to move the heart structure in to view. If you feel you cannot hold your breath don't be concerned, we will adjust as necessary to make sure you are comfortable.

Images are also obtained towards the end of the study with you lying on your back.

At the completion of the study, you will be given a towel to remove any excess ultrasound gel. You will be asked to change back into your clothes and then present to the reception desk for payment and making sure follow up arrangements are in place with our practice, your GP or another treating doctor.
