'a woman' becomes 'bea' ().
'old' becomes 'dated' (dated can mean old or out of date).
'heart' says to take the centre.
The centre of 'dated' is 't'.
'bea'+'t'='BEAT'
(Other definitions for beat that I've seen before include "Pound - defeat" , "Come out better than in a competition" , "buffet" , "Defeat, strike" , "cane" .)
'heart-throb perhaps' is the definition.
I can't tell whether this definition defines the answer.
'a woman's old' is the wordplay.
