Right Juxtaposition of the Atrial Appendages

Abstract

Right juxtaposition of atrial appendages are rare and associated with congenital heart defects. We report 3 cases of right juxtaposition of atrial appendages (RJAA) diagnosed by transthoracic echocardiography. The sub-xiphoid sagittal view, parasternal short axis and apical four chambered views demonstrated RJAA. All 3 cases with RJAA were associated with congenital heart disease. Diagnosis was confirmed by CT angiogram and intra-operative findings in two children who underwent surgical correction. Right juxtaposition of atrial appendages is a rare association with congenital heart defects. Transthoracic echocardiographic assessment may give clues to the diagnosis.
