Best Predictor for Mortality from Biliary Atresia Liver Transplantation Candidates –Cardiomyopathy?

Briefly noted: A recent study (NM Gorgis et al. Hepatology 2019; 69: 1206-18, editorial 940-2 by Elizabeth Rand) indicates that cirrhotic cardiomyopathy (CCM) is very important factor for survival for biliary atresia (BA) patients requiring liver transplantation.

CCM was defined based on two-dimensional echocardiographic criteria: LV mass index ≥95 g/meter-squared or relative wall LV thickness of LV ≥0.42.

Key points:

  • Overall, 11 of 69 patients died, 4 while awaiting liver transplantation and 7 following transplantation.
  • 34 of 69 BA patients in this cohort had BA-CCM
  • All 11 who died had BA-CCM compared with no deaths in the 35 patients without CCM.

My take: Severe BA-CCM needs to be examined further; if severe, it may merit changing allocation policy.
