The pulmonary veins enter the posterosuperior chamber, also termed accessory LA chamber. Typically, the right atrial partition is due to exaggerated fetal eustachian and thebesian valves, which together form an incomplete septum across the lower part of the atrium. This septum may range from a reticulum to a substantial sheet of tissue. Cor triatriatum dexter can be diagnosed at any age, especially if it is incidentally discovered.

The so called “cor triatriatum dexter” represents a remnant of the right valve of the sinus venosus. Further echocardiographic investigations showed an underlying inferior SVD, an incomplete cor triatriatum dexter and a large patent foramen ovale (PFO).

Learn more: http://www.ctsnet.org/article/cor-tri The most widely accepted theory for the cause of cor triatriatum is secondary to an incomplete incorporation of the common pulmonary vein into the posterior aspect of the left atrium. Cor triatriatum is frequently associated with orther cardiac abnormalities such as a PFO, secundum ASD and left SVC to coronary sinus and less commonly with anomalous pulmonary venous connection. Cor triatriatum represents a rare congenital heart malformation consisting of a structure that divides the left or, less frequently, right atrium into two compartments. The abnormal tissue fold, fibromuscular band or membrane are remnants of embryonic structures and may have different dimensions, may be imperforate or have several fenestrations, leading to more or less severe hemodynamic impact. Dec 18th, 2013 - Cor triatriatum dexter is an extremely rare congenital anomaly of the right atrium.

The detection usually occurs after the sequelae of systemic congestion, coagulopathy, and hepatic dysfunction have set in, leading up to a high surgical risk. Cor triatriatum is an extremely rare congenital (present at birth) heart defect. The human heart normally has four chambers, two ventricles and two atria. The two atria are normally separated from each other by a partition called the atrial septum and the two ventricles by the ventricle septum.

Cor triatriatum represents a rare congenital heart malformation consisting of a structure that divides the left or, less frequently, right atrium into two compartments.

Cor triatriatum is a congenital heart defect where the left atrium or right atrium is subdivided by a thin membrane, resulting in three atrial chambers.

Sinus venosus atrial septal defect (SVD) is a rare cardiac abnormality in adults. Particularly, the inferior type is difficult to depict by transthoracic echocardiography because of its infero-posterior location to the fossa ovalis.

Particularly, the inferior type is difficult to depict by transthoracic echocardiography because of its infero-posterior location to the fossa ovalis. Cor triatriatum dexter can occur as an isolated cardiac anomaly or may be associated with pulmonary artery stenosis or atresia, tricuspid valve abnormality, ASD, and Ebstein anomaly. [4] Cyanosis is a very rare presentation as represented by Hoye and colleagues in a neonate with cor triatriatum dexter with cyanosis having significant obstruction to right ventricular inflow.

Incomplete separation of the right atrium may occur when prominent venous valve remnants such as Eustachian valve (EV) or Chiari network (CN) incompletely divided the right atrium (incomplete CTD‐iCTD). Definition. A rare, congenital, non-syndromic, heart malformation characterized by the persistence of the embryonic right valve of the sinus venosus which results in a subdivision of right atrium into two chambers. Clinical manifestations depend on the degree of right atrial septation and the size of sinoatrial orifice and vary from asymptomatic to symptoms of tricuspid valve stenosis, atrial fibrillation, cyanosis, syncope, elevated central venous pressure and right heart failure. ASD: atrial septal defect; iCTD: incomplete cor triatriatum dexter.
