Primary cardiac fibroma in infants: a case report and review of cases of cardiac fibroma managed through orthotopic heart transplant

Abstract

Cardiac fibromas (CF) are the second most common cardiac tumors in children. They can be aggressive tumors despite their benign histopathologic nature, accounting for the highest mortality rate among primary cardiac tumors. CF usually presents a progressive growth and spontaneous regression is rare. Therefore, a complete surgical excision is the preferred therapeutic approach when patients become symptomatic or if mass-related life-threatening complications are anticipated, even in asymptomatic patients. However, some cases are not good candidates for surgical excision due to the impossibility of preserving a normal cardiac anatomy or function after the tumor resection. Orthotopic heart transplantation (OHT) can be an exceptional but adequate alternative for some giant unresectable CF in children. In this article, we report our experience with the case of a 7-month-old infant with a giant unresectable cardiac fibroma who was successfully managed through OHT.
