Key result
An infant prenatally diagnosed with an isolated right ventricular intracardiac teratoma died despite rescue extracorporeal support and partial surgical resection, consistent with previous reports.
Why the study?
Intracardiac teratomas are rare primary tumours, motivating the presentation of a case with unusual presentation and literature review.
Case Report (n=1)
Fetal intracardiac teratomas have a very poor prognosis regardless of prenatal tolerance and tumor size, which is critical information for parental counseling during pregnancy.
Supports counseling on poor prognosis for fetal intracardiac teratomas; extends sparse case evidence while leaving optimal management open.
Intracardiac teratomas are rare primary tumours. We report the case of an infant prenatally diagnosed with an isolated multi-cystic mass developed in the right ventricle causing neonatal refractory ventricular arrhythmia. Despite rescue extracorporeal support and partial surgical resection, he died as almost all the previous reported perinatal intracardiac teratomas whatever the prenatal tolerance and the size of the tumour. The common poor outcome of fetal intracardiac teratomas should be known when counselling parents during pregnancy.

Bellaing et al. (2019) conducted a case report in Perinatal intracardiac teratoma (n=1). Rescue extracorporeal support and partial surgical resection was evaluated on Survival/clinical outcome. An infant prenatally diagnosed with an isolated right ventricular intracardiac teratoma died despite rescue extracorporeal support and partial surgical resection, consistent with previous reports.
