Key result
Intraoperative transesophageal echocardiography identified a prominent Eustachian valve as the cause of preoperative diagnostic error, redefining a presumed sinus venosus ASD as a secundum ASD.

May warrant intraoperative TEE confirmation in discrepant ASD cases; leaves open broader adoption in congenital heart surgery.
Case Report (n=1)
Intraoperative TEE is crucial in congenital heart surgery to confirm anatomy, as structures like a prominent Eustachian valve can mimic a sinus venosus ASD on preoperative imaging.
Miller‐Hance et al. (1997) conducted a case report in Atrial septal defect (n=1). Intraoperative transesophageal echocardiography (TEE) was evaluated. Intraoperative transesophageal echocardiography identified a prominent Eustachian valve as the cause of preoperative diagnostic error, redefining a presumed sinus venosus ASD as a secundum ASD.
