Abstract:
Doppler evaluation of prosthetic valves is a complex process involving assessment of both forward and regurgitant flow. It is important to consider the type of prosthesis, its size, its position, its relationship to the ultrasound beam, and the patient's cardiac output and afterload condition in any evaluation of prosthetic valve function.
