In theory, you can get H&A effect for rather broad range of proportions but it won't mean that the stone is ideal cut.

H&A is an effect of internal or opticall symmetry when all the facets are in perfect alignment. To get a perfect heart shape you also should have lower girdle facets in 76%-80% range.
