Usual arrangement of the atria (cardiac situs solitus) with discordant atrioventricular (AV) connection in a 9-year-old boy. Note the characteristic morphology of the left atrial appendage identifying the location of the morphologic left atrium, which lies on the left of the morphologic right atrium. The inflow of the morphologic right ventricle (RV) lies to the left of the morphologic left ventricle (LV), which indicates L-ventricular loop. Source: Dr. Luc Mertens, Toronto, ON, Canada.
