RESUMO
BACKGROUND: Heart failure (HF) is characterized by significant mortality in both adults and children. Characteristics of pediatric HF are feeding problems, poor weight gain, exercise intolerance, or dyspnea. These changes are often accompanied by endocrine disorders. The main causes of HF are congenital heart defects (CHD), cardiomyopathies, arrhythmias, myocarditis, or heart failure secondary to oncological treatment. Heart transplantation (HTx) is the method of choice for treatment of end-stage HF in pediatric patients. AIMS: This article aimed to summarize the single-center experience in heart transplantation in children. METHODS: Between 1988 and 2021 in the Silesian Center for Heart Diseases in Zabrze, 122 pediatric cardiac transplantations were performed. In the group of recipients with failing Fontan circulation, HTx was performed in 5 children. The study group was evaluated for the postoperative course: rejection episodes depending on the medical treatment scheme, coinfections, and mortality. RESULTS: One-, 5-, and 10-year survival rates between 1988 and 2001 were 53%, 53%, and 50%, respectively. One-, 5-, and 10-year survival rates between 2002 and 2011 were 97%, 90%, and 87%, respectively; between 2012 and 2021 (1-year of follow-up), the survival rate was 92%. The main cause of mortality both in early and late periods after transplantation was graft failure. CONCLUSIONS: Cardiac transplantation in children remains the main method of treatment for endstage heart failure. Our results at both early and long-term posttransplant periods are comparable to those obtained in the most experienced foreign centers.
