In a significant proportion of patients with left-sided heart failure (HF), left ventricular filling pressure (LVFP) may not be estimated using echocardiography, so filling pressure status may remain indeterminate. In these patients, mean right atrial pressure (mRAP) has been suggested as a surrogate of LVFP. The aim of this study was to determine whether high mRAP has prognostic value in patients with HF with indeterminate pressure (IP) and whether mRAP-based reclassification of patients with IP has an impact on outcomes.

Abstract
In a significant proportion of patients with left-sided heart failure (HF), left ventricular filling pressure (LVFP) may not be estimated using echocardiography, so filling pressure status may remain indeterminate. In these patients, mean right atrial pressure (mRAP) has been suggested as a surrogate of LVFP. The aim of this study was to determine whether high mRAP has prognostic value in patients with HF with indeterminate pressure (IP) and whether mRAP-based reclassification of patients with IP has an impact on outcomes.
