Echocardiographic Demonstration of Anomalous Septum in Cor Triatriatum

Cor triatriatum; concerning the nature of an anomalous septum in the left auricle.

The term cor triatriatum is open to criticism but has been used by previous writers and has the merit of being superficially descriptive of a heart in which a transverse septum divides the left auricle into an upper and lower chamber. In 1829, Andral stated that he had seen a heart with three auricles, but he did not describe it. The abnormality is clearly uncommon for, since 1868, when Church ...

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 ...

Three-dimensional transthoracic echocardiographic evaluation of cor triatriatum.

We present an adult patient with cor triatriatum (CTT) due to a left atrial (LA) membrane. Two-dimensional and real-time three-dimensional transthoracic echocardiography (3DE) were performed as well as echocardiographic examination after exercise. These non-invasive modalities provided a comprehensive anatomic and hemodynamic evaluation of the anomaly.

Total anomalous pulmonary venous connection and a restrictive foramen ovale, with left-sided deviation of the atrial septum mimicking left-sided cor triatriatum: echocardiographic misdiagnosis.

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...
