Key result
Nonopacification of the right atrial appendage with right atrial angiocardiography was identified as a new angiographic sign to differentiate other conditions from tricuspid atresia.
Why the study?
Does right atrial angiocardiography help differentiate cor triatriatum dexter and total anomalous systemic venous drainage from tricuspid atresia?

Does right atrial angiocardiography help differentiate cor triatriatum dexter and total anomalous systemic venous drainage from tricuspid atresia?
Nonopacification of the right atrial appendage during right atrial angiocardiography can help differentiate cor triatriatum dexter and total anomalous systemic venous drainage from tricuspid atresia.
May aid differentiation of rare right atrial anomalies; hypothesis-generating case observation requiring prospective validation.
Two patients with the classical clinical, angiographic, and echocardiographic signs of tricuspid atresia are reported, where the correct diagnoses were made at operation; one child had cor triatriatum dexter, the other child total anomalous systemic venous drainage to the left atrium. The literature on cor triatriatum dexter and total anomalous systemic venous drainage is discussed and a new angiographic sign for the differentiation from tricuspid atresia is reported: nonopacification of the right atrial appendage with right atrial angiocardiography.

Hausdorf et al. (1985) conducted a case report in Suspected tricuspid atresia (n=2). Right atrial angiocardiography was evaluated on Differentiation from tricuspid atresia. Nonopacification of the right atrial appendage with right atrial angiocardiography was identified as a new angiographic sign to differentiate other conditions from tricuspid atresia.
