No, it wasn't. Read up on lore. The gods themselves could not destroy it, for the heart was beyond them.

I'll try and get this as accurate as I can :

"The gods tore the heart from the trickster Lorkhan and attempted to destroy it. But the heart simply laughed and said '"You cannot destroy me, for I and Mundus are one and the same. One cannot exist without the other."'

Seing as the universe is indestructible, it makes sense.

Souls are not mortal.
