Fetal cardiac capillary hemangioma triggers transient tachyarrhythmia followed by bradycardia and AV conduction disturbance.
Case Report (n=1)
Cardiac capillary hemangiomas in children are rare tumors that can invade the conduction system, leading to complex arrhythmias including tachyarrhythmia and subsequent AV conduction disturbances.
May prompt extended monitoring for late bradycardia after hemangioma-related tachyarrhythmia; leaves open natural history and surveillance needs.
day after birth. Histopathological examination revealed an undifferentiated capillary hemangioma. The patient was discharged at the age of 86 days, as the tachyarrhythmia and hemodynamic incompetence had subsided; however, bradycardia and intermittent atrioventricular conduction disturbance gradually developed. Capillary hemangioma, a rare primary cardiac space-occupying tumor in children, can invade the conduction system.

Sakamoto et al. (2022) conducted a case report in Fetal cardiac capillary hemangioma (n=1). Fetal cardiac capillary hemangioma caused tachyarrhythmia that subsided by 86 days of age, but subsequently led to bradycardia and intermittent atrioventricular conduction disturbance.
