Huge right ventricle cardiac fibroma in a child patient

In this case, we describe a 9-year-old child who presented with chest pain due to a huge right ventricle fibroma. With the support of cardiopulmonary bypass, the tumor was successfully removed, but to avoid right ventricular rupture and tricuspid valve injury, only a small amount of tumor tissue remained in the myocardial tissue. Pathological examination confirmed that the ventricular tumor was a fibrous borderline tumor. The patient has normal cardiac and tricuspid function at a 3-month follow-up. It is reported that the prognosis of patients younger than 17 years old at the time of diagnosis is poor, and the long-term prognosis of this child needs further follow-up.
