Hemoadsorption Contribution in Failing Fontan Pediatric Heart Transplantation.

Introduction: A systemic inflammatory response is triggered in patients undergoing cardiothoracic surgery with cardiopulmonary bypass (CPB). This response is particularly evident in pediatric patients, especially those of low weight and after undergoing long CPB, and can severely impair the surgical result. Adsorptive blood purification techniques have been proposed to limit this systemic inflammatory response. To test its efficacy, we added the hemoadsorption filter Jafron HA 380 to CPB in a much compromised pediatric patient who underwent heart transplantation.

Methods: A 10-year-old single ventricle patient previously treated with Fontan operation was listed for heart transplantation due to the evidence of failing Fontan condition. He experienced many episodes of cardiac arrest and underwent heart transplantation in much compromised general and hemodynamic conditions. The hemoadsorption filter Jafron HA 380 was used for all the duration of CPB, and the inflammatory biomarker interleukin 6 (IL-6) was assayed.

Results: Postoperative outcome was uneventful and comparable to that of elective pediatric heart transplantation. IL-6 levels showed an impressive postoperative reduction, and after 2 days, the IL-6 level was comparable with a typical uneventful post-transplant course.

Conclusions: The use of hemoadsorption filter can contribute to improve the pediatric transplant results, especially in very high-risk patients.
