Élissalde went to the 2007 World Cup in good form, but was left on the bench for the opener against Argentina. Following a terrible display by his replacement Pierre Mignoni, he was restored as the French made it to the semi finals. He scored a try and kicked 11 conversions for a tally of 27 points in an 87–10 thrashing against Namibia. He kicked the winning conversion in the quarter final against New Zealand, a game which France won 20–18. Élissalde was limited to three appearances in the Six Nations in 2008, including the championship deciding loss to Wales in Cardiff. He gained the last of his 35 caps in November 2008 in a Test against the Pacific Islanders where he had to leave the pitch on a stretcher after 18 minutes when Napolioni Nalaga's high tackle left him unconscious.
