Tissue Doppler Echocardiography is a non-invasive medical procedure that uses ultrasound to examine and measure heart functions, detecting heart dysfunctions and conditions such as valve loss and abnormal communication between the left and right sides of the heart. It can also evaluate the size and shape of the heart, detect regurgitation, and aid in the detection of coronary artery disease. The procedure is commonly used to diagnose heart disease and malfunctions.
Tissue Doppler
Echocardiography
it is a medical procedure that uses
ultrasound
to examine and measure the functions of the heart. Used to determine the speed and direction in which blood is pumped, Doppler technology, in combination with an
echocardiogram
, helps reveal heart dysfunction. By using tissue Doppler echocardiography to establish velocity measurements, clinicians can more accurately assess the function of a patient’s heart valves. Conditions that can be detected with this procedure include communication between the left and right sides of the heart that is abnormal and cardiac
valve
loss.
Other data available through the use of tissue Doppler echocardiography are calculations of cardiac output and the patient’s E/A ratio, a measurement of the time intervals between the pumping and filling phases of the heart. The results of this test may indicate diastolic
heart failure
. Although the term “Doppler” is often used in place of “velocity measurement”, in
imaging medicale
the frequency shift (
Doppler effect
) is not measured. Instead, the phase shift is recorded at the moment the signal arrives.
The echocardiogram subjected to Doppler shift measurement is often referred to by healthcare professionals as a cardiac ECHO. In some cases, the term ECHO is used by itself, while in other cases it may be referred to as “cardiac ultrasound”. The technology uses standard ultrasound approaches to create two-dimensional images of the heart. Newer systems offer real-time imaging with 3D views of the heart in action.
In addition to creating two-dimensional images, tissue Doppler echocardiography can help your doctor evaluate the speed of your blood or the condition of your heart tissue. Using continuous or pulsed wave Doppler ultrasound, vulvular regurgitation (blood leaking through the valves) can be detected. Echocardiography was among the first applications of ultrasound technology in medicine and is among the most common technologies used to diagnose
heart disease
and malfunctions. It is usually administered by cardiac sonographers or physicians with
cardiology
training.
In addition to helping doctors evaluate valve function, tissue Doppler echocardiography is also useful for determining the size and shape of the heart. It can also reveal a backward flow of blood through partially closed heart valves, a condition known as regurgitation. Observation of heart wall movements can aid in the detection of coronary artery disease. The procedure is often used to rule out coronary artery disease when the patient complains of chest pains. Because it is not necessary to break the skin or enter body cavities to perform tissue Doppler echocardiography, it is considered a noninvasive procedure.
