The echocardiographic findings in a patient with cor triatriatum are presented. The preoperative echocardiogram demonstrated an unusual structure behind the mitral valve that moved anteriorly during atrial systole. There was also echocardiographic evidence of abnormalities of mitral valve motion, right ventricular and left atrial enlargement, and pulmonary hypertension. Postoperatively, the unusual echo behind the mitral valve had disappeared and the mitral valve appeared more normal. Left atrial and right ventricular dimension had decreased and the pulmonary valve appeared more normal. Fine diastolic mitral valve fluttering, an abnormal echo behind the anterior mitral valve leaflet moving anteriorly with atrial systole, an abnormal pulmonary valve echogram suggesting pulmonary hypertension, and marked right ventricular and left atrial enlargement were the main echocardiographic findings in our patient.
