{Abstract}: <B>OBJECTIVE: </B>To describe the clinical profile of acute rheumatic fever (ARF) presentations to paediatric cardiology tertiary services in Western Australia (WA).<BR><B>METHODS: </B>A retrospective clinical audit of individuals with confirmed ARF referred to the only paediatric tertiary cardiac service in WA (1 January 1987 to 31 December 2020). Comparisons between inpatient, outpatient, remote and non-remote groups were assessed.<BR><B>RESULTS: </B>Four hundred seventy-one episodes of ARF in 457 individuals (235 male; median age = 8 years) met clinical criteria. The majority were Aboriginal and Torres Strait Islander children (91.2%), with 62.1% living in remote areas. The number of ARF and rheumatic heart disease (RHD) diagnoses per year increased from 1987 to 2017 with notable peaks in 2013 and 2017. The average annual incidence of tertiary-referred ARF in WA of 4-15-year-olds from 1987 to 2020 was 4.96 per 100 000. ARF features included carditis (59.9%), chorea (31%), polyarthritis (30%) and polyarthralgia (24.2%). RHD was evident in 61.8% of cases and predominantly manifested as mitral regurgitation (55.7%). Thirty-four children (7.4%) with severe RHD underwent valvular surgery. 12% had at least one recurrent ARF episode. Remote individuals had more than double the rate of recurrence compared to non-remote individuals (P = 0.0058). Compared to non-remote episodes, remote presentations had less polyarthritis (P = 0.0022) but greater proportions of raised ESR (P = 0.01), ASOT titres (P = 0.0073), erythema marginatum (P = 0.0218) and severe RHD (P = 0.0133).<BR><B>CONCLUSIONS: </B>The high proportion of Aboriginal and Torres Strait Islander Australians affected by ARF/RHD in WA reflects the significant burden of disease within this population. Children from remote communities were more likely to present with concurrent severe RHD. Our study reinforces the persisting need to improve primary and secondary ARF initiatives in rural and remote communities.
