Congenital aneurysm of the left atrium associated with double‐outlet right ventricle in a trisomy‐18 fetus: Case report and literature review

Abstract

Congenital aneurysm of the left atrium is a rare cardiac anomaly, most commonly detected between the 2nd and 4th decades of life in a symptomatic patient. We report a congenital aneurysm of the left atrium diagnosed at 24 weeks of gestational age, associated with other congenital heart diseases and 47XY, +18 karyotype. The literature of the left atrial aneurysm diagnosed by fetal echocardiography is also reviewed in this report.

Congenital left atrial appendage aneurysm: Prenatal diagnosis and outcome of a rare cardiac abnormality

“…3 It is possible to diagnosis LAAA prenatally with fetal echocardiography. [4][5][6][7][8] In this case, the characteristics of the aneurysm in- In our case, the LAAA was detected by prenatal ultrasound confirmed post birth and followed conservatively until further enlargement was seen at 18 months of age. Computed tomography (CT) showed that the aneurysm was compressing the left main bronchus and left superior pulmonary vein.…”

Therefore, once the left atrial appendage is diagnosed, early surgical intervention is generally recommended, even in asymptomatic patients.…”

Prenatal Diagnosis of a Right Atrial Appendage Aneurysm: Case Report and Review of the Literature

“… 2 Ultrasonographic signs of RAA are a large cystic structure linked to the atrium with blood flow between them that can be confused with an aneurysm of the left atrial wall, enlarged coronary sinus, bronchogenic cyst, mediastinal mass, and pericardial effusion. 5 6 Surgical treatment has been reported to have good outcomes, and it is recommended to manage RAA. However, because of the rarity of this entity, a direct comparison of medical treatment with anticoagulation and antiarrhythmic therapy is not available in the current literature.…”
