Key result
Surgical LAA thrombus excision leads to rapid recovery in a term neonate with ventricular dysfunction.
Why the study?
Left atrial appendage thrombosis is exceedingly rare in neonates and may present with nonspecific findings.
Surgical excision of a rare left atrial appendage thrombus in a neonate with ventricular dysfunction led to rapid recovery, emphasizing the need for early echocardiography in subtle neonatal heart failure.
May warrant surgical excision for neonatal LAA thrombus with ventricular dysfunction; hypothesis-generating for this rare presentation.
Left atrial appendage thrombosis is exceedingly rare in neonates and may present with nonspecific findings. We report a term neonate presenting with poor feeding and a gallop rhythm, who was found to have a large left atrial appendage thrombus with ventricular dysfunction. Surgical excision resulted in rapid recovery, highlighting the importance of early echocardiographic evaluation in subtle neonatal heart failure.
