Cor triatriatum sinister is a rare congenital defect in which the left atrium is divided by a fibromuscular membrane into two distinct chambers. Classically, patients present in infancy although in some cases they remain asymptomatic until adulthood. The clinical features on presentation can mimic those of mitral stenosis due to the obstructive properties of the membrane. Cor triatriatum sinist...

Cor triatriatum occurs during embryological development when the common pulmonary vein fails to incorporate in the left atrium (LA) and gives rise to a fibromuscular membrane that divides the LA into 2 chambers: a superior accessory chamber where the pulmonary veins enter, and an inferior one, the “true” LA, with its auricular appendage, which connects with the left ventricle through the mitral...

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...

Pulmonary hemosiderosis is a disorder with unknown cause and characterized by hemosiderin appreciation in alveolar interstitium from decomposed hemoglobin following alveolar capillary bleeding, which finally leads to pulmonary fibrosis. It can be divided into primary and secondary types in terms of its etiology. While primary types are related to autoimmunity, secondary types can be associated ...

1 of 3 DESCRIPTION A 28-year-old woman presented with recurrent syncope, usually precipitated by anxiety. On examination, she had a low blood pressure of 112/72 mm Hg with normal heart sounds and showed no features suggestive of genetic abnormalities. ECG, Holter and treadmill stress tests were normal. Transthoracic ( fi gure 1 ) and transoesophageal ( fi gure 2 ) echocardiography demonstrated ...

Hemihypertrophy syndrome and cor triatriatum are extremely rare pathologies. Hemihypertrophy is defined as complete or partial overgrowth of one of the hemibodies. Cor triatriatum is a congenital heart disease characterized by a membrane which separates the left atrium into two chambers; if that membrane has a restrictive hole, it causes obstruction to blood passage from the pulmonary veins int...

Cor triatriatum sinister is a rare congenital cardiac malformation characterized by a membrane in the left atrium which separates the left atrium into the proximal and distal chambers.Association of cor triatriatum is extremely rare with situs inversus totalis. Here we report a rare case of cor triatriatum sinister with situs inversus totalis in a 5 month old female infant. MeSH: Cor triatriatu...
