Echocardiography is the ultrasound examination of the heart. Depending on the used ultrasound system, echocardiograms can be two-dimensional slices or 3D real-time images of the heart. Based on the ultrasound principles the direction and speed of blood flow can be utilized e.g., to diagnose a leaking or stenosed valve or to identify intracardiac shunts.

Different types of echocardiography:
point transthoracic echocardiography (TTE);
point transesophageal echocardiography (TEE);
point contrast echocardiogram (CE);
point stress echocardiogram.

The transthoracic echocardiogram (images are taken through the chest wall) is a non-invasive, highly accurate and quick assessment of the overall health of the heart.
A more invasive method is to insert a specialized scope containing an echocardiography transducer (TEE probe) into the esophagus, and record images from there. The advantages are clearer images, since the transducer is closer to the heart.
Contrast echocardiogram (CE) is already a valuable tool to delineate endocardial borders, direct invasive procedures, detect intracardiac shunts, assess myocardial perfusion and viability, and quantify coronary flow reserve and blood volumes (see also hemoglobin). The mechanism of microbubble CE is based on the physical principles of rarefaction and compression, leading to volume pulsations of microbubbles, and it is this change that results in CE signal.
Stress echocardiograms are echocardiography exams used for detection of coronary artery disease.

M-Mode EchocardiographyMRI Resource Directory:<br> - Cardiac -
 
M-mode (Motion-mode) ultrasound shows the motion of cardiac structures. M-mode echocardiography records the amplitude and rate of motion of a moving structure in real time by repeatedly measuring the distance of the object from the single transducer at a given moment. The single sound beam is transmitted and reflected signals are displayed as dots of varying intensities, creating lines across the screen. It yields a one-dimensional image, sometimes called an 'ice pick' view of the heart.
M-mode echocardiography is used to detect valvulopathies (calcifications, etc.) and cardiomyopathies (dyskinesis, aneurysm, etc.).

Transthoracic EchocardiographyMRI Resource Directory:<br> - Cardiac -
 
(TTE) Transthoracic echocardiography is a common type of cardiac ultrasound and is used to evaluate the size and function of the heart.

Indications:
list_point assessment of the cardiac size, shape and function;
list_point pathological changes of the myocardium;
list_point function of the cardiac valves;
list_point pericardial fluid;
list_point congenital heart defects.
TTE requires no sedation or special patient preparation. After the application of ECG electrodes and ultrasound couplant, the probe is maneuvered over the chest in the area adjacent to the breast bone and under the left breast, to provide the different views of the heart. Usually the images will be obtained lying relaxed on the left side. Other views can be sampled lying on the back with the knees bent, or sitting in an upright position.

Bicycle Stress EchocardiographyMRI Resource Directory:<br> - Cardiac -
 
Bicycle stress echocardiography can be used instead of treadmill. Bicycle exercise is particularly useful for patients with valvular heart disease or for evaluated pulmonary artery pressures. It is also used as a substitute for treadmill exercise testing when the heart performance at each stage of exercise needs to be assessed and the patient is capable of bicycle exercise. Bicycle stress echocardiography has no additional risk compared to routine exercise.

Transesophageal EchocardiographyMRI Resource Directory:<br> - Cardiac -
 
(TEE) Transesophageal echocardiography provides a superior view of cardiac anatomy compared with transthoracic echocardiography. TEE is performed by the introduction of a probe attached to a fiberoptic endoscope into the esophagus. Caused by the position close to the heart e.g., clot finding and the view of the mitral valve are improved.

Indications:
list_point aortic atherosclerotic disease;
list_point aortic dissection;
list_point artificial mitral valves;
list_point clots inside the left atrium;
list_point cardiac infections;
list_point masses or clots in the heart.
The piezoelectric crystal creating the acoustic power is mounted on the gastroscope that must be swallowed by the patient. This endoscopic transducer is miniaturized to approximately the size of a fingernail. Usually the probe is in place for an average of 15 minutes, to numb the surface a topical anesthetic is sprayed into the throat, in addition a conscious sedation is recommended.
