Introduction Right atrial pressure (RAP) is a haemodynamic variable that provides important diagnostic and prognostic information in both cardiovascular and pulmonary disease patients ( 1 , 2 , 3 ). Despite its usefulness in routine clinical

qualitative assessment of right atrial pressure (RAP). Previous studies have demonstrated good correlation across patient populations but only moderate precision of absolute PASP values calculated from TR velocity (TRV)max ( 11 , 12 , 13 , 14 ). This is

absolute measurement of TRV can result in significant changes to the estimation of the RV-RA pressure gradient. Secondly, in order to obtain an estimate of pulmonary artery systolic pressure (PASP), an estimate of the right atrial pressure (RAP) (derived
