What is it

A colour Doppler echocardiogram is a non-invasive, diagnostic test that analyses the anatomy and working of the heart as well as visualising and hearing the blood flow in real time

What is its purpose

It allows the measurement and evaluation of blood flow through the chambers and valves of the heart. Possible disease or damage to the cardiac muscle, valves, arteries, veins and pericardium can be detected easily as can congenital heart diseases and tumours.

It is also used for the realization, control, monitoring and evaluation of patients who have had valve surgery. 

How is it done

This procedure requires no preparation nor special care; it consists of placing a small probe, called a transducer, on the chest of the patient, this sends ultrasonic waves through the skin and tissue producing an echo in the heat chamber. A computer is used to read and interpret these waves, producing an image of the heart walls and valves. Thanks to the use of colour, the different directions of blood flow are reflected, simplifying the interpretation of the images. During the test the technician will move the transducer in circles and vary the pressure to obtain images of different places and parts of the heart.
