What is a Transthoracic Echocardiogram (Echo)?

A Transthoracic Echocardiogram, or ‘Echo’, is a type of ultrasound scan used to look at the heart structure, primarily the valves and ventricular function.

A transducer emits high-frequency sound waves that create returning echoes when they bounce off heart structures and blood cells. These returning echoes are picked up by the electronic crystals in the probe and turned into a moving image that is displayed on a monitor while the scan is carried out.
