<![CDATA[The liver has a complex dual blood supply, which makes it more resistant to hepatocyte necrosis due to hemodynamic disturbances. Prior hemodynamic data has indicated that an elevation in right atrial pressure in patients with heart failure may result in aberrant cholestatic markers of liver function. This cross-sectional study examined the correlation between ejection fraction and liver function in 85 children (1–18 years) with congenital or acquired heart disease. Echocardiography assessed TAPSE, Tricuspid Regurgitation (TR), E/A ratio, and Left Ventricular Ejection Fraction (LVEF), while liver function was evaluated using total bilirubin and SGPT. Results showed a strong negative correlation between TAPSE and total bilirubin (p=0.001, r= -0.725) and a moderate positive correlation between tricuspid regurgitation and total bilirubin (p=0.001, r=0.548). The E/A ratio, LVEF, and total bilirubin showed weak correlations, while TAPSE and SGPT had a weak negative correlation (p=0.025, r= -0.243). No correlation was found between TR, E/A ratio, LVEF, and SGPT. A strong correlation existed between heart failure severity and total bilirubin (p=0.001, r=0.603), but not with SGPT. These results highlight the correlation between the severity of heart failure and liver impairment by indicating that decreasing right ventricular function correlates to elevated total bilirubin.]]>
