Key result
Pre-operative 2-D transthoracic echocardiography accurately diagnosed structural heart diseases in children, demonstrating a sensitivity and positive predictive value of 94.5% compared to surgical findings.
Why the study?
In resource-poor environments where advanced investigations are costly and scarce, 2-D TTE may be the sole diagnostic modality, warranting an audit of its accuracy against intra-operative findings in children with structural heart diseases.
Does pre-operative 2-D TTE accurately diagnose structural heart diseases compared to intra-operative findings in children?

Does pre-operative 2-D TTE accurately diagnose structural heart diseases compared to intra-operative findings in children?
Effect estimate: Sensitivity 94.5%, PPV 94.5%
Pre-operative 2-D TTE is highly accurate and concordant with surgical findings for diagnosing structural heart diseases in children in a resource-poor setting.
Ujunwa et al. (2022) conducted an observational in Structural heart diseases (n=55). Pre-operative 2-D Transthoracic Echocardiography (2-D TTE) vs. Intra-operative surgical findings was evaluated on Sensitivity and positive predictive value of 2-D TTE compared to intra-operative findings (Sensitivity 94.5%, PPV 94.5%). Pre-operative 2-D transthoracic echocardiography accurately diagnosed structural heart diseases in children, demonstrating a sensitivity and positive predictive value of 94.5% compared to surgical findings.
