Echocardiography is a non-invasive diagnostic tool which can be performed on children of all ages including foetuses and new-borns, due to the fact that no radiation is involved No historical bibliometric study of influential papers in paediatric echocardiography has been performed yet, so our study was aimed to close this gap. References Publication Years Spectrography (RPYS), more precisely CitedReferenceExplorer (CRE) software tool was employed to achieve this aim. 35 influential papers were identified. Validation showed that both, the RPYS method and CRE tool performed satisfactorily.
