Transthoracic echocardiography (TTE)

Ultrasound imaging of the heart through the chest wall, used to assess the structure and function of the heart chambers, valves and pericardium.

What is it?

Transthoracic echocardiography is a non-invasive imaging examination that uses ultrasound to visualize the heart in real time. A probe is placed at various positions on the chest and emits high-frequency sound waves which, by reflecting off the cardiac structures, produce a detailed image of the heart in motion. This examination is one of the most important in cardiology because it provides valuable information about the anatomy and function of the heart. It assesses the size and wall thickness of the heart chambers, the contractile function of the left ventricle (ejection fraction), the functioning of the four heart valves, the possible presence of pericardial effusion and many other parameters. Using the associated Doppler techniques, echocardiography also measures blood flow through the valves and chambers, detects valve leaks (regurgitation) and narrowings (stenoses), and assesses intracardiac pressures. Color Doppler provides an intuitive visualization of normal and abnormal blood flow. At the Clinique Pasteur in Tunis, echocardiography is performed with latest-generation ultrasound machines offering exceptional image resolution. The examination is carried out and interpreted by experienced echocardiographers, guaranteeing an accurate and reliable diagnosis.

When is it indicated?

Heart murmur heard on auscultation

When the doctor hears an unusual sound through the stethoscope, the ultrasound shows the heart valves and determines whether the murmur is harmless or linked to an abnormality.

Heart failure or unexplained shortness of breath

If the heart seems to lack strength or if breathlessness persists with no obvious cause, the examination directly measures the heart's ability to pump blood.

Chest pain

When chest pain occurs, the ultrasound helps check that the heart muscle is contracting normally and guides the diagnosis.

Assessment after a myocardial infarction

After a heart attack, the examination assesses the areas of the heart that may have been affected and checks that pumping strength remains satisfactory.

Monitoring of known valve disease

When a heart valve leaks or narrows, regular ultrasound scans track its progression and help choose the right time for any intervention.

High blood pressure (looking for effects on the heart)

Long-standing high blood pressure can thicken and tire the heart muscle: the ultrasound checks whether the heart shows any signs of this.

Assessment of cardiomyopathy

In cases of heart muscle disease, the examination specifies the shape, thickness and function of the heart to guide treatment.

Screening for congenital heart disease

In children and adults alike, ultrasound can detect a heart malformation present from birth, completely painlessly.

Preoperative cardiac assessment

Before certain operations, the examination makes sure the heart is fit to withstand the anesthesia and the planned procedure.

Assessment of suspected infective endocarditis

If an infection of the heart valves is suspected, particularly in cases of persistent fever, the ultrasound looks for signs of valve involvement.

Preparation

1No special preparation is required
2There is no need to fast
3Wear clothing that allows easy access to the chest
4Bring the results of previous echocardiograms for comparison
5Bring your prescription and a list of your medications

Procedure

1

The patient lies on their back and then on their left side on the examination table

2

A conductive gel is applied to the chest to help transmit the ultrasound waves

3

The cardiologist moves the probe over different areas of the chest (acoustic windows)

4

Images of the heart are recorded from different angles and in different modes

5

Doppler measurements of blood flow are taken

6

The patient may be asked to change position or breathing during the examination

7

The gel is wiped off at the end of the examination

Duration

20 to 40 minutes

Results

Results are available immediately. The cardiologist writes a detailed report with the measurements and conclusions, given to the patient the same day or sent to the prescribing physician.
