Dopplers
What is a doppler?
Doppler echocardiography is a procedure which uses ultrasound technology to
examine the heart. An echocardiogram uses high frequency sound waves to create
an image of the heart while the use of Doppler technology allows determination
the speed and direction of blood flow by utilizing the Doppler effect.
An echocardiogram can, within certain limits
, produce accurate assessment of the direction of blood flow and the
velocity of
blood and cardiac tissue at any arbitrary point using the Doppler
effect. One of
the limitations is that the ultrasound beam should be as parallel to the
blood
flow as possible. Velocity measurements allow assessment of cardiac
valve areas
and function, any abnormal communications between the left and right
side of the
heart, any leaking of blood through the valves (valvular regurgitation),
calculation of the cardiac output and calculation of E/A ratio (a
measure of
diastolic dysfunction). Contrast-enhanced ultrasound using gas-filled
microbubble contrast media can be used to improve velocity or other
flow-related
medical measurement.
