The literature's primary focus has been on the LV with little attention given to the RV. This study aimed to investigate echocardiographic right ventricular indices in the detection of ACR and to evaluate their utility as prognostic indicators of graft integrity.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We performed a retrospective chart review of children with biopsy\u2010proven ACR following orthotopic heart transplant and an echocardiogram within 24\u00a0h of biopsy. Selected echocardiographic markers were compared at baseline, during ACR, and at follow\u2010up.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Forty\u2010eight patients (56% male) had a total of 84 ACR episodes. Decrease in RV FAC (mean\u00a0\u2212\u00a017.1%, <jats:italic>p<\/jats:italic>\u00a0&lt;\u00a0.001) and TAPSE (mean\u00a0\u2013\u00a08.9%, <jats:italic>p<\/jats:italic>\u00a0&lt;\u00a0.001) with increase in left ventricular posterior wall thickness in diastole and systole (LVPWTd) (mean\u00a0+\u00a09.0%, <jats:italic>p<\/jats:italic>\u00a0=\u00a0.012) and LVPWTs (mean\u00a0+\u00a08.3%, <jats:italic>p<\/jats:italic>\u00a0=\u00a0.016) were found during ACR. Interestingly, these parameters improved following the episode of rejection. Additionally, these markers were compared after recovery between children with and without graft failure. RV dysfunction (FAC and TAPSE) and changes in LV posterior wall thickness were not found to have prognostic significance for graft integrity in children with heart transplantation.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>RV echocardiographic functional parameters should be considered as valuable adjuncts in rejection surveillance. Further, the presence of RV dysfunction does not have prognostic significance for graft integrity but is reversible as ongoing damage was not detectable by
