To assess the relationship of late diastolic pulmonary valve motion to motion of adjacent cardiac structures, we performed two-dimensional and dual M-mode echocardiography on 15 pulmonary normotensive (group A) and nine pulmonary hypertensive subjects (group B). Simultaneous pulmonary valve and posterior aortic wall a-waves were less prominent in group B than in group A (p less than 0.001), and their amplitudes were linearly related within each group (r = 0.83). Analysis of two-dimensional studies confirmed a relationship between pulmonary valve and posterior aortic wall late diastolic motion. No subject had independent presystolic motion of the pulmonary valve within the pulmonary artery. Subjects with shallow a-waves had impaired left atrial emptying compared with those with normal a-wave amplitudes (p less than 0.01). We conclude that the pulmonary valve a-wave does not represent independent valvular displacement, but rather, reflects motion of the entire cardiac base. Variations in a-wave morphology may result, at least in part, from the effects of altered ventricular geometry and compliance on left atrial emptying.
