Plain-English summary
A 5-year-old mixed breed dog and a 7-year-old Labrador were diagnosed with cor triatriatum dexter, a rare heart defect where a septum forms in the right atrium. The mixed breed showed symptoms that led to a diagnosis through ultrasound and other tests. The mixed breed underwent successful surgery to remove the septum and improve heart function, while the Labrador had additional complications and surgery was not performed.

Abstract
Cor triatriatum dexter is a congenital heart defect in which the embryologic right sinus venosus valve persists as a septum within the right atrium. Cor triatriatum dexter was diagnosed in 2 dogs on the basis of clinical signs, two-dimensional echocardiography, and cardiac catheterization. In 1 of the dogs, the condition was successfully treated by surgical resection of the intra-atrial septum. In the second dog, the defect was associated with an incomplete persistent cranial left vena cava and Ebstein's anomaly; surgery was declined.
