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 ...

Cor triatriatum sinistrum is a rare congenital disorder defined as a division of the left atrium by a diaphragmatic membrane resulting in two left atrial chambers. The membranous division of the atrium can be partial or complete and can affect either atrium, with involvement of the right atrium referred to as cor triatriatum dexter. The presence of fenestrations within the membrane allows for c...

Cor triatriatum sinister is a rare congenital cardiac anomaly with an incidence of between 0.1 and 0.4% [1,2] whereby the left atrium is functionally and anatomically divided into two separate chambers by a thin membrane. Although there are a limited number of reports of successful ablation of left atrial focal tachycardia and simple pulmonary vein isolation in individuals with cor triatriatum ...

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...

An atrial septal aneurysm (ASA) is a rare but well-recognized abnormality of uncertain clinical relevance. It is a localized bulging of the inter-atrial septum into either or both atria during the cardiac cycle. ASA has been reported as an unexpected finding during autopsy but may also be diagnosed in living patients by echocardiographic techniques.We present a 37-year-old woman with a recurren...

Cor Triatriatum Sinistrum is a congenital anomaly in which the left atrium is divided into 2 parts by a fold of tissue, a membrane, or a fibromuscular band. Classically, the proximal (upper or superior) portion of the left atrium receives the venous blood, whereas the distal (lower or inferior) portion is in contact with the atrioventricular valve and contains the atrial appendage and the true ...
