What is an echocardiogram?
An echocardiogram or cardiac ultrasound is a diagnostic tool for looking closely at the heart as well as inside and around it. The ultrasound machine uses high frequency sound waves to create live images, allowing veterinarians to get an idea of what the heart looks like and how it is functioning in real time. This provides information about the size, shape, and function of the heart, its four chambers, the heart valves, and surrounding structures, such as the pericardial sac. During this procedure your veterinarian will use some doppler technologies to assess the blood flow and pressure gradients between the heart chambers which are major drivers of heart changes.
Why would my pet need this procedure?
If your pet was recently diagnosed with a heart murmur or is suspected to have heart disease based on signs seen on x-rays or by coughing or fainting, your pet may need an echocardiogram. The echo can show if the heart is working properly, and if not, what the problem is. Medications and treatments for heart disease are tailored to the individual, so understanding the problem correctly helps provide the best treatment.
Echocardiograms can also be used to determine if treatments are helping or if a change in dosage or new medications are required.
