Background/aim
Liver cirrhosis is associated with several cardiac abnormalities. There have been few studies of these abnormalities in cirrhotic children post-liver transplantation (LT). The purpose of this study was to evaluate cardiac abnormalities in cirrhotic children pre- and post-LT.
Methods
All cirrhotic children <15 years of age on a waiting list for LT underwent pre-LT echocardiography to evaluate left ventricular (LV) dimension, mass, and function. Repeated studies were performed at 1–2 and 3–6 months post-LT.
Results
A total of 20 cirrhotic children (median age 21.5 months [8–108 months], 11 female [55 %]) were enrolled in the study. Most patients had biliary atresia (75 %) and decompensated cirrhosis, with a median pediatric end-stage liver disease score of 19.5 (14–28). Two patients subsequently died, at 1 and 4 months post-LT. Echocardiography was re-evaluated in 17 and 18 patients at 1–2 months and 3–6 months post-LT, respectively. Prior to transplant, most patients had cardiac abnormalities, including LV enlargement (50 %), increased LV mass (95 %), abnormal LV geometry (95 %), hyperdynamic LV systolic function (60 %), LV diastolic dysfunction (60 %), and high cardiac index (75 %). At 3–6 months post-LT, no significant decrease in cardiac abnormalities was noted; however, cardiac parameters including LV dimension in diastole index and z-score, LV mass index, and relative wall thickness were significantly decreased.
Conclusions
Most cirrhotic children had cardiac abnormalities, including LV enlargement, increased LV mass, abnormal LV geometry, and LV dysfunction. These abnormalities tended to improve post-LT. We suggest that echocardiography should be performed in all cirrhotic children.
