Suggests echo-Doppler utility for jugular valve assessment in HF; leaves open clinical implications pending larger studies.
The echocardiographic literature contains very scant reference to incompetence of the valve in the internal jugular vein. However, we found frequent Doppler evidence of such incompetence, especially in patients with congestive failure. This incompetence manifests as a variety of color Doppler and pulsed Doppler patterns, illustrated here in 3 patients.
