Lung ultrasound (LUS) has emerged as a non-invasive, radiation-free, and highly accurate alternative for assessing PO in CHD patients, offering real-time bedside evaluation.

to evaluate the utility of LUS as a bedside and non-invasive diagnostic tool for assessment of pulmonary overflow in children with congenital heart diseases (CHD).

This is a cross-sectional study with an analytical component that was carried out on 45 children with congenital heart diseases having pulmonary overflow. All children in this study were subjected to medical history, complete general examination, complete chest and cardiac examination, lung US, chest-X ray (CXR), pulmonary to systemic blood flow ratio (Qp/Qs) ratio via echocardiography and high-resolution CT chest.

There was significant positive correlation between cardiothoracic ratio, Qp/Qs ratio and lung US degree (p=0.01 and 0.01, respectively). There was statistically significant relation between lung US degree and CXR results (p=0.001) and between CT findings and lung US findings (p=0.027). Sensitivity (Sn) of lung US in diagnosing pulmonary overflow was 76.9% and total accuracy 55.6% in comparison with presence of interstitial lung thickening by CT. Sensitivity of lung US in diagnosing pulmonary overflow was 100% and total accuracy 55.6% in comparison with presence of ground glass haziness by CT.

The current research highlighted the value of LUS in assessment of pulmonary overflow as bedside noninvasive and radiation free diagnostic tool compared to chest X-ray, CT, and echocardiography with high sensitivity (Sn) and …
