Imminent Fetal Cardiac Tamponade by Right Atrial Hemangioma

Abstract

A fetus presented with a large pericardial effusion caused by a right atrial transmural tumor. Correct prenatal diagnosis by use of targeted fetal echocardiography indicated that treatment was not required until the gestational age of 36 weeks. At that time, cesarean section was performed because early signs of imminent cardiac tamponade developed ("swinging heart"). At birth, the pericardial effusion was drained with a percutaneous drain. Elective surgical resection was performed on day 6 of life. Histologically, the tumor was a benign capillary hemangioma.

A Review of Findings in Fetal Cardiac Section Drawings

“…A small amount of pericardial fluid or a small effusion, as in case 14 (Figure 16), can be present normally 63 or can be a sign of many conditions, such as trisomy 21, a hypoplastic left heart, teratoma, 64 rhabdomyoma, hemangioma, 65 tachyarrhythmia, chorioangioma, sacrococcygeal teratoma, 66 an atrioventricular septal defect, cardiomyopathy, Rh disease, renal agenesis, posterior urethral valves, and twin-twin transfusion syndrome. 67,68…”

Hemangioma as a rare cause of a neonatal cardiac tumor resulting in inflow obstruction of the tricuspid valve

“…There are reports of tumors diagnosed prenatally in screening ultrasound examinations [3]. Pregnancy in our patient had been unremarkable.…”

“…Bunlardan ilki, düşük kardiyak "output" ve dolayısıyla hemodinamik instabilite, ikincisi ise fetal pulmoner hipoplazidir. 4 İntratorasik kavitenin daralmış olmasına bağlı olarak fetal akciğer büyümesi etkilenebilir. 5 Ekibin tüm bu komplikasyonlara karşı hazırlıklı olması gereklidir.…”
