In this looping movie heart beat and blood flow through the living chicken heart can be seen in realtime. The movie is a lateral view of the chicken embryo (Hamburger-Hamilton stage 17) head and body with the heart loop seen on the right and dorsal aorta on the left. This an edited extract version (looped and small) of the original full abnormal heart movie.

Removal (at Hamburger-Hamilton stage 14/15) of neural crest that normally contributes to the heart outflow generates heart abnormalities visible in this later embryo (stage 17) movie. Early abnormal cardiac looping can generate heart anomalies such as tetralogy of Fallot or double outlet right ventricle. This an edited extract version (looped and small) of the original full abnormal heart movie (Neuralcrestablatedheart.mov).

In the full movie of abnormal embryonic chicken heart, blood flow through the heart can be seen in a series of realtime samples of the embryo over an extended (10 hour) time period. The movie is a lateral view of the embryo (head and body) with the heart loop seen on the right and dorsal aorta on the left. In the neural crest-ablated embryo, the outflow limb is displaced ventrally/cranially and turned rightward so that both inflow and outflow limbs are visible from the right side.
