1Department of Cardiothoracic Surgery, The Prince Charles Hospital, Chermside, Queensland, Australia.
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.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
