Actually, rather a point seems to be made that Padme doesn't die of the choke, which is backed up by a scan I saw from the RotS kids' book that says Palpatine is lying to Anakin when he says Anakin killed her. According to spoilers all damage to her body is repaired, but for reasons that baffle the med-droids she's still dying anyway. And a fellow A/P-er on TFN actually wrote LFL on the matter and got a response from Lynne Hale that says straight up that Padme dies of a broken heart.

That still doesn't make me much happier on the choke aspect, though.
