    We read with interest the article by Khiabani et al.[1], where the authors suggested TCPC power loss could affect exercise performance in Fontan patients. Using indexed Power Loss, "iPL", instead of unadjusted PL, they report higher iPL correlated with worse exercise. We believe that this approach is misleading leading to wrong conclusions.

    iPL was:

    iPL=PL/(pQ^3/BSA^2 )

    where PL, p, Q, and...
