Pulmonary Artery Systolic & Diastolic Pressures
In the absence of pulmonary disease, increased PA pressures may be used to infer the presence of elevated LV filling pressures.
The peak velocity of the tricuspid regurgitation (TR) jet by continuous-wave (CW) Doppler together with systolic right atrial (RA) pressure are used to derive PA systolic pressure.
