ABSTRACT
Background. The absolute number of patients presenting with failure of the hemi-Fontan or Fontan circulation for cardiac transplantation (cTx) will continuously rise. We aimed to analyze the intraoperative differences in patients undergoing cTx for a failing hemi-Fontan or Fontan circulation (group A) with those undergoing cTx for cardiomyopathy and congenital heart disease (group B). Methods. Data of patients undergoing cTx during a 10-year period were compared between group A and group B patients. Results. cTx was performed in 83 patients (group A, n = 21; group B, n = 62). Surgical times including median incision-suture time (549 minutes vs 386 minutes, P < .05) and median organ ischemia time (305 minutes vs 233 minutes, P < .05) were longer in group A patients. After weaning off cardiopulmonary bypass a higher median modified Vasoactive Inotropic Score (16 vs 10, P < .05) was necessary in group A patients. During surgery more fresh frozen plasma (44 mL/kg vs 20 mL/kg, P < .05), platelet concentrates (20 mL/kg vs 14 mL/kg, P < .05), and coagulation factor concentrates were given in group A patients. Mortality during the first 90 days after cTx was higher in group A (23.8% vs 6.5%, P < .05). Conclusion. Patients undergoing cTx for a failing hemi-Fontan or Fontan circulation are challenging. They require an intensive vasoactive and inotropic support; furthermore, special attention should be paid to the management of bleeding complications. cTx for this group of patients is associated with higher 90 days mortality.
