| 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. |
