Right atrial appendage aneurysm in a fetus-Does precise prenatal diagnosis matter?

Introduction: Congenital malformations of the right atrium-aneurysms and diverticulaare rare heart defects with only a few cases having been described prenatally. Early diagnosis of these anomalies is extremely important due to the possibility of such serious complications such as supraventricular arrhythmia, thromboembolic events and sudden death.

Topic Description: Although each of these anomalies is well known, there are still significant discrepancies in diagnosis.

Band neutrophil sign: A strong first-trimester ultrasound marker of combined duodenal and esophageal atresia.

Objectives: To reveal a first-trimester sonographic marker associated with combined duodenal and esophageal atresia (DA and EA).

Methods: This retrospective study included four patients referred to our department in the first trimester due to fetal stomach anomaly. In the literature, we found 20 additional cases of combined DA and EA with four of them to be revealed at 12 weeks.
