  The ATLAS detector has been used to search for high-mass states decaying into
a single high momentum lepton and missing transverse energy, such as new heavy
charged gauge bosons. The latest search results for a W Prime boson decaying to
lepton plus neutrino in 1.04 fb^-1 of proton-proton collisions at a center of
mass energy of 7 TeV produced at the Large Hadron Collider are presented.
