Notice that in the image you want to reproduce, the mesh lines on the back-facing side of the heart are not rendered. The quickest and easiest way I could think of to reproduce that aspect of the plot was to use isosurface to render a white surface just beneath the inside surface of the mesh, blocking the view of the back side
