Abstract

Doppler ultrasound can be extremely useful in quantitating valvular aortic stenosis, but the problems and pitfalls of the method must be appreciated to avoid being misled clinically. A substantial learning period is essential, and careful, often long, exams using multiple patient positions and transducer windows are required. The difference between peak and peak-to-peak gradient and its implications in reporting Doppler results must be comprehended as well as the potential for errors due to a large angle between the Doppler beam and the direction of the ascending aortic jet. Finally, the shape of the CW spectrum should be used as a guide to preventing clinically important over- or underestimation of catheterization gradients.
