Why the study?
Quadricuspid aortic valve and cor triatriatum are rare congenital cardiac anomalies.
This case highlights a rare presentation of quadricuspid aortic valve with bilateral atrial divisions and notes limitations in current nomenclature for atrial partitions.
Alerts clinicians to rare quadricuspid aortic valve with bilateral atrial divisions; leaves open refinement of nomenclature systems.
BACKGROUND: Quadricuspid aortic valve and cor triatriatum are rare congenital cardiac anomalies. METHODS: We describe a rare case of quadricuspid aortic valve with dividing membranes in the left and right atria. RESULTS: The patient underwent surgery with resection of the dividing membrane in the left atrium and aortic valve replacement. CONCLUSION: Management is based on symptoms of obstruction due to the dividing membranes in the atria and the severity of aortic valve dysfunction. This case also highlights the limitations in current nomenclature when describing atrial partitions.
