COR TRIATRIATUM is an uncommon congenital cardiac anomaly that is characterized by division of the left atrium into two separate chambers by a fenestrated membrane. This condition typically presents in infancy or early childhood, and can be associated with other cardiac anomalies. A smaller number of adult cases have been reported in the literature. We present the case of a patient with cor tri...

  Cor triatriatum is an acyanotic congenital heart disease. We present a rare case of cor triatriatum sinistrum in a 6-month-old female infant who was presented with cyanosis and failure to thrive. The 2D transthoracic echocardiography and the Doppler color flow imaging showed a proximal venous chamber communicating to the distal left atrium  through restrictive opening to the low-pressure, dis...

Cor triatriatum sinistrum is a rare congenital cardiac malformation, accounting for about 0.1-0.4% of all congenital heart diseases and characterized by the presence of a fibromuscular membrane that subdivides the left atrium into two chambers in the classical form. While classic cor triatriatum in most patients can be observed during the neonatal period or early infancy, it is very rare in adu...

This is the report of a cor triatriatum dextrum, detected in utero and surgically treated at 10 days of age. We have been unable to find a similar report of neonatal correction in the literature.
