echocardiography

(ek?o-kard?e-og'ra-fe) [ echo + cardiography ]
A noninvasive test that uses ultrasound to visualize cardiac structures. The heart's chambers, ejection fraction, valves, and wall motion can be evaluated, and intracardiac masses or clots can often be seen. echocardiographic (e-o-graf'ik), adjective

dobutamine stress echocardiography

Abbreviation: DSE
Echocardiography for coronary artery disease in which dobutamine is given to patients to increase the workload of the heart, and then the heart is evaluated with ultrasonic imaging. Regions of the heart that do not receive adequate blood flow (ischemic regions) contract poorly during the stress of the test but normally when the patient is at rest. Heart muscle that does not contract normally either at rest or with stimulation has been injured previously by myocardial infarction.

Doppler echocardiography

See: Doppler echocardiography

multidimensional visualization echocardiography

An experimental echocardiographic technique using computer technology for three-dimensional visualization of cardiac structures. This becomes four-dimensional when time is used to impart the cinematic perception of motion.

stress echocardiography

Echocardiography of segments of heart muscle that do not move properly when a patient with coronary artery disease exercises or takes a vasodilating drug (e.g., adenosine or dipyridamole). Stress-induced impairments in regional heart muscle activity are used as markers of obstructions in specific coronary arteries.

TRANSESOPHAGEAL ECHOCARDIOGRAPHY

transesophageal echocardiography

Abbreviation: TEE
A technique for obtaining echocardiographic images in which the ultrasonographic transducer is introduced into the esophagus. TEE is useful in detecting cardiac sources of emboli, prosthetic heart valve malfunction, endocarditis, aortic dissection, cardiac tumors, and valvular and congenital heart disease. See: illustration

transthoracic echocardiography

Abbreviation: TTE
Echocardiography of the heart and great vessels by means of an ultrasonic transducer placed on the chest wall. Sound waves are transmitted to the underlying organs (e.g., the heart or aorta), and an image is constructed from those that rebound toward the transducer.

dobutamine stress echocardiography

Abbreviation: DSE
Echocardiography for coronary artery disease in which dobutamine is given to patients to increase the workload of the heart, and then the heart is evaluated with ultrasonic imaging. Regions of the heart that do not receive adequate blood flow (ischemic regions) contract poorly during the stress of the test but normally when the patient is at rest. Heart muscle that does not contract normally either at rest or with stimulation has been injured previously by myocardial infarction.
