AI summary — for doctors, generated from the abstract only

A 14-year-old with cardiac tamponade had a right atrial composite hemangioendothelioma treated with resection and chemotherapy and no recurrence at 6 months.

What was studied

Case report of an adolescent with hemorrhagic pericardial effusion and a large right atrial mass.

Key findings

The mass was excised under bypass.
Histopathology favored composite hemangioendothelioma of low malignant potential.
PET-CT showed no residual disease; gemcitabine/docetaxel adjuvant given.

Clinical relevance

Primary cardiac vascular tumors are rare.

Who should care

Pediatric Cardiology

Limitations

One case with short follow-up.

Consider cardiac tumor with unexplained hemorrhagic effusion.

Abstract

Primary cardiac vascular tumors are rare in children. We report a 14-year-old girl with hemorrhagic pericardial effusion, cardiac tamponade, and a large right atrial mass. Echocardiogram identified the lesion and tamponade physiology. Pericardial drainage and stabilization preceded computed tomography (CT) and cardiac magnetic resonance imaging. The mass was excised under cardiopulmonary bypass, and the atrial defect was reconstructed with an autologous pericardial patch. Histopathology and immunohistochemistry favored composite hemangioendothelioma of low malignant potential. Postoperative FDG PET-CT showed no residual or metastatic disease. Adjuvant gemcitabine/docetaxel-based chemotherapy was given after multidisciplinary review. Six-month echocardiogram showed no recurrence.
