To the Editor: In “The Heart of the Matter” (Nov. 4 issue),1 Thibault comments that aortic valvular insufficiency can be underestimated if the Doppler probe is not perpendicular to the direction of the jet. In fact, the best Doppler spectral display is obtained when the angle of the probe is either parallel to or within 20 degrees of the direction of the jet of blood. Aside from this slight technical matter, the discussion was thoroughly enjoyable. To the Editor: Thibault presents an excellent, methodical clinical discussion of a patient in Clinical Problem-Solving. The patient had a normal echocardiogram four years.
