        abstract = {Background: Congenital atrial septal aneurysm (ASA) is a rare cardiac anomaly characterized by excessive mobility or bulging of the interatrial septum. While commonly asymptomatic, ASA can occasionally lead to complications such as arrhythmias, embolism, or hemodynamic disturbances, necessitating careful evaluation and follow-up.
Case Presentation: We report a case of a 22-year-old second gravida mother who presented at 40 weeks of gestation with A fetal ultrasound at 37 weeks revealing cardiomegaly with thickened atrioventricular valves, while earlier scans were unremarkable. The mother had a normal vaginal delivery of a female baby weighing 3.1 kg. The newborn, requiring routine resuscitation, was admitted to the NICU for monitoring due to antenatal concerns. Postnatal examination showed no murmurs, respiratory distress, or cardiac symptoms, and the baby was clinically stable. A 2D echocardiogram revealed a prominent atrial septal aneurysm without obstruction to blood flow. Given the absence of significant cardiac manifestations, a conservative approach was taken, and the baby was discharged on direct breastfeeding with a plan for follow-up after one month.
Discussion: Congenital ASA is often an incidental finding on echocardiography, with most cases remaining asymptomatic. In neonates, it is generally a benign condition requiring periodic follow-up rather than immediate intervention. The management strategy is determined by factors such as aneurysm size, mobility, and the presence of associated cardiac defects. In this case, the absence of clinical symptoms supported a conservative management plan, consistent with current guidelines.
Conclusion: This case highlights the importance of prenatal and postnatal echocardiographic evaluation in detecting congenital ASA. While usually benign, appropriate follow-up is crucial to monitor for potential complications. A structured follow-up plan is necessary to ensure the timely identification of any evolving cardiac concerns.},
