Correlation Between the Inferior Vena Cava/Aorta (Ivc/Ao) Ratio and Serum Lactate Levels in Children With Renal Disorder.

Background: Acute kidney injury (AKI) is common in critically ill children in the PICU, with incidence rates from 2.5% to 58%, impacting mortality and hospital duration. Early AKI detection is vital, but conventional hemodynamic monitoring often lacks specificity.

NT-proBNP levels as a predictor of higher left ventricular end-diastolic pressure in children with small perimembranous ventricular septal defect.

Introduction: The decision to close small ventricular septal defect is still controversial. Previous study showed that ventricular dysfunction in adulthood is correlated with small perimembranous ventricular septal defect. N terminal pro B-type natriuretic peptide (NT-proBNP) is a neurohormone secreted primarily from the ventricles in response to increased left and right ventricular pressure and volume load.

Risk factors for severe pulmonary regurgitation after repair of tetralogy of Fallot with transannular patch.

Background: Severe pulmonary regurgitation may result in right ventricular volume overload and decreased right ventricular function. Severe pulmonary regurgitation can be predicted prior to repair of tetralogy of Fallot. The aim of this study was to determine the risk factors for severe pulmonary regurgitation in repaired tetralogy of Fallot with transannular patch.
