A cardioid is a shape that is very similar to this, and I thought I'd try and approximate it. It turns out its not a cardioid, but its very close, and can be approximated with the parametric equations:
where a = 1.36 and c = 1.17

Perhaps this can be also used? It has similar shape and parametrization, but different place for coefficients, and is more general then cardioid.
Limacon?
