Can the pulmonary valve be reliably detected using a specific echocardiographic technique?
This paper describes a reproducible echocardiographic technique for visualizing the pulmonary valve and assessing its motion patterns.
A relatively easy, reproducible ultrasonic technique for detection of the pulmonary valve is described. Echoes are obtained from the aorta one interspace above the valve, and the beam is angled slowly toward the patient's left shoulder until the pulmonary valve is seen. This valve shows a wide range of cusp motion patterns. Echograms appear to reflect the diastolic pressure gradient between the pulmonary artery and the right ventricle.
Gramiak et al. (Sat,) studied this question.
