Case ReportsDivided left atrium in association with tricuspid atresia and discordant ventriculo-arterial connections.
Division of the morphologically left atrium is a rare abnormality, constituting around 0.1% of congenital heart disease. It may coexist with other cardiac abnormalities, and this association may obscure its recognition. We report an uncommon association with tricuspid atresia and discordant ventriculo-arterial connections, the latter dominating the clinical picture. Accurate diagnosis was made by transthoracic cross-sectional echocardiography, and the patient was referred to surgery without need for cardiac catheterisation.
