Clinical data indicate that intracardiac blood flow patterns during cardiac morphogenesis are a significant etiology. We used the left atrial ligation (LAL) model in the chick embryo to test the hypothesis that LAL immediately alters intracardiac flow streams and the biomechanical environment, <jats:italic>preceding<\/jats:italic> morphologic and structural defects observed in HLHS. <jats:bold><jats:styled-content>Results:<\/jats:styled-content><\/jats:bold> Using fluorescent dye injections, we found that intracardiac flow patterns from the right common cardinal vein, right vitelline vein, and left vitelline vein were altered immediately following LAL. Furthermore, we quantified a significant ventral shift of the right common cardinal and right vitelline vein flow streams. We developed an <jats:italic>in silico<\/jats:italic> model of LAL, which revealed that wall shear stress was reduced at the left atrioventricular canal and left side of the common ventricle. <jats:bold><jats:styled-content>Conclusions:<\/jats:styled-content><\/jats:bold> Our results demonstrate that intracardiac flow patterns change immediately following LAL, supporting the role of hemodynamics in the progression of HLHS. Sites of reduced WSS revealed by computational modeling are commonly affected in HLHS, suggesting that changes in the biomechanical environment may lead to abnormal growth and remodeling of left heart
