I just assumed that they dissected through the heart to unfold it. In humans the heart is ‘compact’ and there’s no real way to unfold it without cutting through cardiac muscle but, the heart embryological develops from a tube that folds over itself so you can theoretically ‘unfold’ it.

Interesting, but this isn’t an entire heart, is it? Only half? Or isn’t a human heart? Human hearts have separate left and right pairs of chambers which pump oxygenated and de-oxygenated blood separately. Or am I mistaken?

Considering this picture of a whole heart you are probably correct

There are two “halves” but they’re nowhere near symmetric. The two parts nested inside one another in (a) are the “halves”.

Isn’t that why there are 2 loops at the bottom? One for the left and one for the right?
