The stylized heart shape, ♥ (or <3, A.K.A the "happy cyclops with a Cat Smile" face, as an emoticon), is a classic visual metaphor. But, that's for the tropes in the Heart index. This page is for when the heart symbol appears and isn't part of any of those tropes.
Something of note: According to The Other Wiki, the exact origin of the ♥ symbol remains controversial, since it doesn't take a doctor to realize that it looks nothing like an actual human heart; however, its existence as a stylized symbol seems to go back at least to medieval Europe, or maybe ancient Roman North Africa.
Wicked Heart Symbol is a subtrope, for when the heart symbol is associated with villainy. Say It with Hearts is one as well, the ♥ symbol is the only symbol that works with that trope, no anatomical hearts can be used for that, unless it's being played with.

- In Conor Kostic's novel Saga: Ghost's symbol is a ♥, and is always represented that way. Why is it that symbol? We don't know. As she says in Saga when painting aircars:
I settled for a pale blue sky with fluffy white clouds as my background, and then filled it with floating red ♥s. Not much of a statement, I know, unless you think about how there are millions of aircars out there, and they are all a standard simple monochrome. To introduce playfulness and individuality is in itself a kind of subversion. Well, thats if my choice needed any justification.

The symbol was downgraded a little after their make-over as 1980's big-haired rock chicks performing stadium rock.
