- W3100657151 abstract "Introduction: Cirrhotic cardiomyopathy is a hemodynamic complication of cirrhosis resulting in cardiac dysfunction. It remains poorly characterized in children. Our aim was to assess cardiac function using speckle tracking echocardiography (STE), a marker of subclinical cardiac dysfunction, in patients undergoing liver transplant (LT) and correlate it with their post-operative (op) clinical course. Methods: This is a retrospective study of pre-LT echocardiograms performed on pediatric patients (pts) with cirrhosis at a single tertiary care center who received a LT. Demographic clinical and echocardiographic data was collected and STE was performed by a single observer using TomTec system. Descriptive data was expressed as mean (SD) and number (%). The relationship between clinical data and echocardiographic variables was assessed using Pearson correlation coefficient. Significance was set at P value < 0.05. Results: Twenty-three pts underwent LT between 03/2013-12/2019 with median age 7.5 (IQR 0.1, 17) years and 31 % with biliary atresia. Five patients were listed as status 1A/1B. Their mean natural pediatric/model end-stage lived disease (PELD/MELD) score was 15. Their pre-LT echocardiogram showed normal left ventricular (LV) ejection fraction and normal right ventricular (RV) fractional area change. Tricuspid annular plane systolic excursion (TAPSE) was abnormal in 50% of pts. While LV global longitudinal strain (GLS) (23 ± 3%) and LV circumferential strain (27 ± 4%) were normal, RV GLS was abnormal in 65% of pts (22 ± 3%). There was no correlation between echocardiographic parameters and post-operative LT course (length of stay, duration of mechanical ventilation, surgical complications). Conclusions: Children undergoing liver transplant have RV dysfunction as evidenced by abnormal TAPSE and RV GLS on speckle tracking echocardiography. Echocardiographic parameters do not correlate with the immediate post-LT clinical status." @default.
