Hemoadsorption Contribution in Failing Fontan Pediatric Heart Transplantation.

Area of Science:

• Cardiovascular Surgery
• Pediatric Cardiology
• Biomedical Engineering

Background:

• Pediatric cardiothoracic surgery with cardiopulmonary bypass (CPB) can trigger a systemic inflammatory response, particularly in high-risk patients.
• This inflammatory response can negatively impact surgical outcomes.
• Adsorptive blood purification is explored as a method to mitigate this response.

Observation:

• A 10-year-old pediatric heart transplant recipient with a failing Fontan circulation and compromised condition was treated.
• The Jafron HA 380 hemoadsorption filter was integrated throughout the cardiopulmonary bypass (CPB) period.
• Interleukin-6 (IL-6), an inflammatory biomarker, was monitored.

Findings:

• The patient experienced an uneventful postoperative recovery, comparable to elective pediatric heart transplants.
• IL-6 levels demonstrated a significant reduction post-surgery.
• Postoperative IL-6 levels normalized within two days, aligning with typical uneventful transplant courses.

Implications:

• Hemoadsorption filtration may enhance outcomes in pediatric heart transplantation.
• This technique shows promise for improving results in very high-risk pediatric transplant recipients.
• Further research into adsorptive techniques in pediatric cardiac surgery is warranted.
