Color Doppler, as well as spectral Doppler, is used to visualize any abnormal communications between the left and right sides of the heart, any leaking of blood through the valves (valvular regurgitation), and estimate how well the valves open (or do not open in the case of valvular stenosis).
The Doppler technique can also be used for tissue motion and velocity measurement, by tissue Doppler echocardiography.
Conscious sedation and/or localized numbing medication may be used to make the patient more comfortable during the procedure.Not only can an echocardiogram create ultrasound images of heart structures, but it can also produce accurate assessment of the blood flowing through the heart by Doppler echocardiography, using pulsed- or continuous-wave Doppler ultrasound.This allows assessment of both normal and abnormal blood flow through the heart.A specialized probe containing an ultrasound transducer at its tip is passed into the patient's esophagus.
This allows image and Doppler evaluation from a location directly behind the heart. Transesophageal echocardiograms are most often used when transthoracic images are suboptimal and when a more clear and precise image is needed for assessment.This is a noninvasive, highly accurate, and quick assessment of the overall health of the heart.This is an alternative way to perform an echocardiogram.Colors are used to represent the velocity and direction of blood flow.
