I deleted by mistake an item

Hi, what can I do? I was looking for transmog items and I deleted an heroic feet item by mistake. I was with lag at the time I done it, dont know if have something to do with it. I am so sad about this. Feets where heroic, obtained from icc. Please tell me you can help me recover them.
Thank you

They are lost forever in the twisting nether. But I'm sure the boss who dropped those feet has another copy ready for you.
