Cardiac hemangioma in a difficult anatomical location presented with ventricular tachycardia. A rare case report

Refractory Fetal and Neonatal Supraventricular Tachycardia Associated With Mitral Valve Mass

Primary cardiac tumors in children are rare and mostly benign but can cause significant cardiovascular complications, including arrhythmias. We present a rare case of fetal and neonatal refractory supraventricular tachycardia linked to a probable mitral valve hemangioma, resulting in severe neonatal and maternal morbidity. Despite challenges, pharmacological therapy ultimately successfully managed the condition, highlighting the importance of individualized treatment in such complex cases.

Fetal cardiac capillary hemangioma resulting in tachyarrhythmia

We present the case of a fetus with cardiac capillary hemangioma in the right atrial cavity. The tumor showed dramatic growth between the 28^th and 32^nd week of gestation and resulted in tachyarrhythmia. The patient was born at the 33 weeks of gestation weighing 2430 g via urgent cesarean section because the rapidly growing cardiac tumor caused incessant tachyarrhythmia, pericardial effusion, and fetal circulatory incompetence. Coronary angiography revealed that the right coronary artery drained into the tumor. Due to hemodynamic deterioration, the patient underwent subtotal resection of the tumor on the 2^nd 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.

A rare pediatric case of pedunculated cardiac hemangioma of the left ventricle

A 12-year-old male child with atypical chest pain and fatigue since past 3 months underwent cardiac magnetic resonance (CMR) imaging for suspicious globular mobile mass detected in the left ventricle on a transthoracic echocardiography. CMR revealed peripheral vascular blush on the first pass perfusion images with centripetal progressive intensely bright enhancement on late gadolinium-enhanced images. Further confirmation and histological diagnosis of the tumor was made through transaortic aortic resection of the mass.
