I don't think they are parts of the heart, no. The heart cannot be destroyed by a god, so it couldn't be by Red Mountain.
My theory is they are rocks from the heart of Red Mountain where Dagoth Ur and the Heart resided. They were in the presence of the Heart for so long that they absorbed a tiny fragment of it's divine power. Thus, they are able to revive the dead.
Not the heart, just whispers of the power that once was.
