  Let $A$ be a truncated polynomial ring over a complete discrete valuation
ring $\mathcal{O}$, and we consider the additive category consisting of
$A$-lattices $M$ with the property that $M\otimes \mathcal{K}$ is projective as
an $A\otimes \mathcal{K}$-module, where $\mathcal{K}$ is the fraction field of
$\mathcal{O}$. Then, we may define the stable Auslander-Reiten quiver of the
category. We determine the shape of the components of the stable
Auslander-Reiten quiver that contain Heller lattices.
