Figure 19

Atrioventricular septal defect with a common atrioventricular valve in dextroisomerism with left dominance. (A) In the postero-superior view of both atria with anatomically right characteristics, the valve ring is displaced toward the left ventricle, and there is an interatrial band typical of this atrial situs (arrow). (B) The two-dimensional 4-chamber echocardiographic image with color Doppler shows the same characteristics evident in the anatomic specimen with the shunt across the atrioventricular septal defect. Abbreviations as before.
