Patient Preparation

What is an echocardiogram?

Transthoracic echocardiogram (or “echo”) images the heart and blood flow using ultrasound. We assess the structure and function of the heart. Patients may be referred for an echo to look at the following pathology:

• assess the function of the heart valves and check for regurgitation

• assess the size, structure, function of the heart

• assess for stenosis (narrowing) of the heart valves and large external vessels

• identify presence of tumours, blood clots, and inflammation of the pericardium

• identify other forms of heart disease and changes to any of the above over time.

What happens during an echocardiogram?

Patients will be asked to undress to the waist and wear a gown for modesty. The sonographer will attach 3 ECG electrodes to the patient before asking them to lie on their side on the exam table. The room is darkened to better allow the sonographer to see the ultrasound images. The sonographer applies conductive water based gel and moves a small transducer around the patients chest wall. The patient may be asked to briefly hold their breath or move slightly to improve imaging, and apart from the pressure of the probe on the chest there is nothing else to feel and no health risks to the patient.

How long does echocardiography take?

Approximately 30- 45 minutes.
