Right Atrial

Also written as RA.

Elevated right‑atrial pressure → systemic venous congestion → JVP, oedema, ascites

What our notes say

Elevated right‑atrial pressure → systemic venous congestion → JVP, oedema, ascites (Heart failure: which tests and why)
Venous return pathways (jugular veins, superior/inferior vena cava, hepatic veins): Elevated right‑atrial pressure transmits back to the jugular veins (raised JVP) and hepatic veins (congestive hepatomegaly). (Approach to Cardiovascular Symptoms and Examination)
Jugular Venous Pressure (JVP): Elevated JVP indicates increased right atrial pressure, common in cardiogenic pulmonary oedema. (Pulmonary oedema and ARDS)
Jugular Venous Pressure (JVP): Elevated, often with a prominent 'a' wave (right atrial contraction against a stiff RV) and sometimes a prominent 'v' wave (tricuspid regurgitation). (Pulmonary hypertension and cor pulmonale)
Haemodynamics from RHC: Higher mPAP, higher PVR, lower cardiac index, higher right atrial pressure indicate more severe disease. (Pulmonary hypertension and cor pulmonale)
Right atrial and ventricular diastolic pressures rise first due to their lower filling pressures, leading to the characteristic haemodynamic compromise. (Pericarditis, effusion and tamponade)
