If the heart tube bends to the left instead of the right, then the heart is displaced to the right and develops in a mirror image of its normal state.

In cases where there is a transposition of other viscera (such as the liver), known as dextrocardia with situs inversus, there is a relatively small chance of any other cardiac abnormalities.  Assuming there are no associated vascular abnormalities, then the heart functions normally.

In cases where the heart is the only organ which is transposed, known as isolated dextrocardia, there are usually other severe cardiac abnormalities.
