I assume you are using Hamapatch.
Your problem is that you are using only 8 points to make a heart, you need
more.
The problem at the bottom is an effect of the "only 8 points" and the way
you closed the patches.

In the following 3 images you can see how I did it, when I made a jewel:
Image 1 and 2 shows that a heart shape must have more than 8 points to work
The jewel was done using the default eight point curve, scaling and
extruding it. Nothing else.
The image 3 shows a render done in povray 3.5 xbeta.

For Hamapatch, there are some tricks and tips, and tutorials, and the manual
and models and...
at http://www.geocities.com/hamapatch

Anyway, if you want to do it with math, I remember there was an isosurface
that
looked exactly as a heart, don't have the source at hand (though someone
sure will tell you


Hope this helps.
