Case in brief
A fetal congenital right atrial appendage aneurysm (RAAA) was diagnosed unusually early in the first trimester, with characteristic echocardiographic features showing a cystic structure connected to the right atrial chamber. The patient underwent comprehensive follow-up for 2 years postnatally, during which a potential association with chromosome 1 abnormalities was noted, indicating a possible genetic component in the condition's pathogenesis.
What made this case unusual
The early diagnosis of RAAA in the first trimester is atypical, as such cases are usually identified in the third trimester.
Diagnostic / clinical pearl
Clinicians should consider the possibility of congenital right atrial appendage aneurysm in early pregnancy, especially when echocardiographic findings suggest a cystic structure in the right atrium.
Why it matters
This case highlights the importance of early detection of cardiac anomalies and suggests a potential genetic link that may warrant further investigation.
