Graphs with no even holes and no sector wheels are the union of two chordal graphs

Sivaraman conjectured that if $G$ is a graph with no induced even cycle then there exist sets $X_1,X_2\subseteq V(G)$ satisfying $V(G)=X_1\cup X_2$ such that the induced graphs $G[X_1]$ and $G[X_2]$ are both chordal. We prove this conjecture in the special case where $G$ contains no sector wheel, namely, a pair $(H,w)$ where $H$ is an induced cycle of $G$ and $w$ is a vertex in $V(G)\setminus V(H)$ such that $N(w)\cap H$ is either $V(H)$ or a path with at least three vertices.
