Instead of staying right next to one another like they're supposed to, cells from the left and right ventricle might mix at some point early on, possibly causing a crack in the wall between the two chambers of the heart.

While the conventional wisdom has been that congenital heart defects occur late in the formation of the organ, we now think that the defects likely result from this very first decision involving the division between the left and right ventricles.

For example, cells in the left ventricle, the chamber of the heart that pumps blood to the body, are destined to serve that purpose within the first few days of development in an embryo.
