Agitated saline contrast echocardiography reveals cor triatriatum dexter.

We present the case of a 54-year-old man who had an unusual finding in contrast echocardiography with agitated saline. Partition of the right atrium in two compartments, an opacified and a non-opacified one, was noted. Further assessment with a transesophageal echocardiogram revealed the presence of a membrane in the right atrium, with the final diagnosis being cor triatriatum dexter.
