Is it possible for atrial flutter to cause cardiac arrest?

Not from a flutter: Atrial flutter is when the atrium beat 2, 3, or 4 times for every time the heart beats. You run a small increased risk of stroke because blood will pool in the atrium and shoot to the brain later on. I have no heart of a case where aflutter caused a cardiac arrest.

Cardiac arrest: Cardiac arrest is a term when the heart can't pump any blood. Atrial flutter rarely causes this problem unless there is very fast conduction into the lower part of the heart or if the atrial flutter degenerated into another rhythm condition (this may occur in patients with significant structural heart disease).
