Tissue Doppler echocardiography
Tissue Doppler echocardiography (TDE) is a medical imaging technique used in cardiology to measure the velocity of myocardial tissue motion. It is a type of echocardiography that uses Doppler effect to generate imaging of the movement of tissues and body fluids.
Overview[edit | edit source]
Tissue Doppler echocardiography is a non-invasive procedure that uses ultrasound waves to create images of the heart. It is used to assess the function of the heart's chambers and valves, and to detect abnormalities in the heart's structure and function. The technique is based on the Doppler effect, which is the change in frequency of a wave in relation to an observer moving relative to the source of the wave.
Procedure[edit | edit source]
During a TDE procedure, a transducer is placed on the chest, which sends out high-frequency sound waves. These waves bounce off the heart and return to the transducer as echoes. The echoes are then converted into images on a screen, showing the heart's chambers and valves in motion. The velocity of the myocardial tissue motion is measured, providing information about the heart's function and structure.
Applications[edit | edit source]
Tissue Doppler echocardiography is used in various clinical settings, including:
- Diagnosis of heart disease
- Evaluation of heart failure
- Assessment of valvular heart disease
- Monitoring of cardiac surgery patients
- Evaluation of congenital heart disease
Limitations[edit | edit source]
While TDE is a valuable tool in cardiology, it has some limitations. These include:
- Difficulty in obtaining good quality images in patients with poor acoustic windows
- Dependence on the angle of insonation
- Inability to provide information on transmural differences in myocardial function
