They prefer temps to remain above 40F but they can tolerate light freezes.
Leaf drop is very common at this point.and is to be expected. I'd wait until
all danger of cold temperatures have passed to assess how much damage was
done and do remedial pruning at that time. How long it tolerated these
conditions will have a bearing on how well it comes back.

I agree with Pam. Don't add injury to insult. Leave it alone
until you begin to see any new growth buds. (if any).
If any top parts are obviously dead, ie mushy/black,
you could remove those.
