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

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 Sinistrum Presenting as Cyanotic Congenital Heart Disease A Rare Case Report

  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: congenital stenosis of the common pulmonary vein.

Cor triatriatum is the term given to a rare congenital abnorTnality of the heart in which a septum separates what is apparently one of the atria into upper posterior and lower anterior chambers. With few exceptions, the septum has always been present on the left side of the heart. Other names given to the same anomaly naturally reflect the authors' views concerning the nature and origin of the ...

Pseudo Cor Triatriatum Sinistrum due to Dilated Coronary Sinus in Association with Supramitral Ring

We herein describe a 34-year-old woman with a persistent left superior vena cava (PLSVC) impinging on the posterior wall of the left atrium, subdivided by a membrane at the distal part of the impingement. In this patient, a much dilated coronary sinus due to the PLSVC resulted in a membrane-like structure in the posterior wall of the left atrium with the appearance of the cor triatriatum in tra...

Cor triatriatum and lipomatous hypertrophy of the interatrial septum in the elderly: a case report

Cor triatriatum is a rare congenital heart defect characterized by the presence of a fibromuscular membrane dividing the left atrium into two distinct chambers. Lipomatous hypertrophy of the atrial septum is an infrequently observed benign abnormality caused by large fatty tissue deposits in the interatrial septum. An increased incidence of atrial arrhythmias is described in both pathologies, w...
