I'm a little stuck... Click here to teach me more about this clue!

'lose the heart' is the definition.
I can't judge whether this defines the answer.

'elvis left out to create trouble' is the wordplay.
'left' becomes 'l' (common abbreviation).
'out' indicates named letters should be taken away.
'to create trouble' becomes 'cerate' (I can't justify this - if you can you should believe this answer much more).
'elvis' with 'l' removed is 'evis'.
'evis'+'cerate'='EVISCERATE'

'as' acts as a link.

Can you help me to learn more?

(Other definitions for eviscerate that I've seen before include "Remove essential parts" , "Draw" , "Disembowel" .)

I've seen this clue in The Irish Times.
