Ultrasound examination of the heart is a non-invasive technique..
It allows visualisation of the internal structures of the heart (valves, muscle, and blood vessels) as well as the structures adjacent to the heart (great vessels and pericardium).
Cardiac Ultrasound is currently the best method of determining causes of heart murmurs and rapid changes in the size of the heart.
Pets receiving cardiac ultrasound will have a small portion of hair removed from under the right arm and are placed with their right side down on an elevated table. This positioning provided the best view of the heart. In critical patients, the study may be done on both sides of the chest and in a standing or sternal position.
In some cases, other structures may be viewed with ultrasound including fluid accumulation outside of the lungs, some tumours associated with the heart or lungs, and tumours outside of the heart and lungs, but contained within the chest cavity.
