• sound waves
  • When the transducer is placed on the chest at certain locations and angles, the ultrasonic sound waves move through the skin and other body tissues to the heart tissues, where the waves bounce or "echo" off of the heart structures. (nyhq.org)
  • By inserting the transducer in the esophagus, TEE provides a clearer image of the heart because the sound waves do not have to pass through skin, muscle, or bone tissue. (nyhq.org)
  • artery
  • Certain conditions of the heart, such as mitral valve disorders, blood clots or masses inside the heart, dissection (tear) of the lining of the aorta (the artery which carries oxygenated blood from the heart to the body), and implanted prosthetic (artificial) heart valves are better visualized and assessed with TEE. (nyhq.org)
  • heart's
  • M-mode echo is useful for measuring heart structures, such as the heart's pumping chambers, the size of the heart itself, and the thickness of the heart walls. (nyhq.org)
  • Also, Doppler can detect abnormal blood flow within the heart, which can indicate a problem with one or more of the heart's four valves, or with the heart's walls. (nyhq.org)
  • 3-D echo shows enhanced views of the heart's anatomy and can be used to determine the appropriate plan of treatment for a child with heart disease. (nyhq.org)
  • chest
  • For example, obesity or pulmonary disease (emphysema or chronic obstructive pulmonary disease, also known as COPD), may interfere with the ability to obtain adequate images of the heart when the transducer is placed on the chest wall. (nyhq.org)
  • time
  • The live or "real time" images allow for a more accurate assessment of heart function by using measurements taken while the heart is beating. (nyhq.org)
