Echocardiography

Standard Trans-Thoracic Echocardiography (Echocardiogram)

Echo Cardiograph

This is an ultrasound test which allows the Cardiologist to take accurate pictures of the heart muscle, the pumping chambers and the heart valves. A probe is placed on the chest wall and an inaudible ultrasound beam passes out from the probe, reflects back from the structures within the heart and allows the cardiologist to build up an accurate image of the heart. A variety of views are taken to look at the heart structures. When these views are completed, a Doppler analysis is performed to analyse blood flow from chamber to chamber and across valves. More specialised analyses can be done looking at particular areas of the heart muscle, it’s movement and its relaxation. The whole procedure takes about 30 minutes and is non invasive.

An echocardiogram is normally used to look at the heart pumping function, look for narrowing or leakiness of the valves and is used to check for fluid around the heart. It can look for signs of infection within the heart and on the heart valves (Endocarditis). It can also be used to see if there are any perforations or holes in the membranes dividing the sides of the four heart chambers, for example a Patent Foramen Ovale (PFO), Atrial Septal Defect (ASD) or Ventricular Septal Defect (VSD). These more complicated tests may need a small drip placed in the arm to allow injection of tiny bubbles. These help the ultrasound to see small holes in the heart.
