The aim of this study was to investigate the possible suitability of the calibrated automated thrombography to determine the coagulation status of pediatric patients with congenital heart disease. Thrombin generation was measured in 60 patients with congenital heart disease using the calibrated automated thrombography and compared to data using standard coagulation parameters such as prothrombin, antithrombin, tissue factor pathway inhibitor, prothrombin fragment 1.2 (F 1.2), and activated partial thromboplastin time. A significant positive correlation was observed between prothrombin and the endogenous thrombin potential (P < 0.01; r = 0.295) as well as between prothrombin and peak height (P < 0.01; r = 0.581). A significant negative correlation was seen between tissue factor pathway inhibitor and endogenous thrombin potential (P < 0.01; r = -0.480) and between tissue factor pathway inhibitor and peak height (P < 0.01; r = -0.234). No statistically significant correlation was found between antithrombin and parameters of continuous thrombin generation. Significant correlation was seen neither between activated partial thromboplastin time and F1.2 nor between activated partial thromboplastin time and prothrombin. The data presented here indicate that calibrated automated thrombography measurements determine thrombin generation more accurately and therefore reflect better the coagulation status of pediatric patients with congenital heart disease then standard global coagulation assays such as activated partial thromboplastin time.
