Related to contrast echocardiography: stress echocardiography
the injection of contrast media of high echo reflectants (for example, bubbles) to outline a chamber or delineate a shunt within the heart.

Injection of contrast media of high echo reflectants (e.g., bubbles) to outline a chamber or delineate a shunt within the heart.
recording of the position and motion of the heart walls or internal structures of the heart and neighboring tissue by the echo obtained from beams of ultrasonic waves directed through the chest wall.
Echocardiography is based on the same principle as the oceanographic technique of depth-sounding; that is, it utilizes ultrasound to delineate anatomical structures by recording on a graph the echoes from the heart structures. It is particularly useful in demonstrating, without danger to the patient, valvular and other structural deformities of the heart which formerly required cardiac catheterization or some other elaborate procedure for accurate diagnosis. See also ultrasonography.
microbubbles in liquid are used as a vascular contrast medium. When injected intravenously in a selected or non-selected location, these can be tracked to demonstrate abnormalities of blood flow.
the ultrasound probe is mounted on a flexible endoscope and is positioned in the esophagus over the base of the heart, thus enabling unique viewing projections of structures in this area.
