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 dexter (CTD) is an extremely rare congenital condition arising from the persistence of the right valve of the sinus venosus. It divides the right atrium (RA) into 2 separate chambers.

ASD: atrial septal defect; iCTD: incomplete cor triatriatum dexter. (0.36MB). Unlike in other series, 4 in our experience this abnormality is associated with complications during percutaneous closure of the ASD: the device was embolized in 2 patients and contraindicated in a further 2. extreme case, cor triatriatum dexter (CTD), in which the right atrium is completely divided into 2 compartments by a membrane that restricts ﬂow toward the right ventricle. CTD can be associated with right ventricular hypoplasia, pulmonary atresia, and Ebstein abnormality.3,4 The redundant eustachian valve combined with septal defect can lead The additional finding of an incomplete or partial division of the right atrium is also a relatively rare cardiac abnormality. The so called “cor triatriatum dexter” represents a remnant of the right valve of the sinus venosus.

During attempted percutaneous closure, the balloon disrupted the membrane and revealed that the defect had no inferior rim, precluding secure placement of an Amplatzer Septal Occluder. Cor triatriatum results from the incomplete absorption of the common pulmonary vein, which is normally reabsorbed during the development of a fetus and becomes a part of the left atrium 7). The incomplete absorption results in the formation of an appendage which subdivides the left atrium into 2 chambers.

The incomplete absorption results in the formation of an appendage which subdivides the left atrium into 2 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.
