Cor triatriatum is a rare congenital cardiac anomaly consisting of a left atrial membrane dividing the atrium into proximal and distal chambers. The anomaly usually presents in childhood, but can present later in life, in which case it is often associated with mitral regurgitation. We report a patient in whom cor triatriatum was found coincidentally by intraoperative transesophageal echocardiography before surgery for severe mitral regurgitation. An interesting finding was preservation of antegrade systolic pulmonary vein flow by Doppler possibly due to shielding of the pulmonary veins from the regurgitant jet by the left atrial membrane.
