Cor triatriatum: diagnosis by MR imaging

Cor triatriatum dexter: two-dimensional echocardiographic diagnosis.

Cor triatriatum dexter is a malformation resulting from lack of normal regression of the embryonic right valve of the sinus venosus. In this situation, the right atrium is divided by a membrane into two chambers. Two-dimensional echocardiography was used in the antemortem diagnosis of this rare cardiac anomaly in a neonate. Associated cardiac lesions were also documented. The patient died, and ...

Cor triatriatum sinister.

C triatriatum is a very rare congenital cardiac anomaly with no known associated genetic abnormalities. Cor triatriatum is generally an isolated anomaly but may be associated with anomalous pulmonary venous return in approximately 10% of patients, patent ductus arteriosus, left superior vena cava, ventricular septal defects, Shone syndrome, tricuspid atresia, Ebstein malformation, atrioventricu...

Cor triatriatum dexter in adults?

Rev Esp Cardiol. 2010;63(12):1510-6 1515 On the other hand, in the fetus and in childhood it is exceptional to find an obstructive CTD without associate anomalies, and in our experience it is also exceptional to find it associated with right-sided heart malformations. That perception is corroborated by the lack of description of this issue, limited to a few cases published in literature.4-6 In ...
