Do you mean the label has a picture of a heart, or the bottle is heart-shaped? You may be able to find the scent by searching by color -- check out this tool:
(Note-- some are listed by the the color of an opaque bottle and some by the color of the perfume in a clear glass bottle)
Hover over the bottle and the name will appear.
Edit: And if you click on the bottle the database listing for that bottle appears.
