This systematic review aims to synthesize literature on the use of 4D flow CMR in assessing right atrial and right ventricular haemodynamics.
Conducted a systematic search of Scopus for observational studies on 4D flow CMR of right heart function in adults.
Included data on RA flow dynamics, RV flow components, KE, EL, and haemodynamic parameters synthesized narratively.
Used the AXIS tool for quality assessment of included studies.
Seventeen studies involving 894 participants met eligibility criteria, including both healthy individuals and patients with pulmonary hypertension.
RA flow dynamics indicated a dominant vortex pattern in healthy individuals, disrupted in disease states.
RV flow components showed decreased direct flow and increased residual volume in disease conditions, with KE reflecting age, sex, and disease-specific changes.
