From 1997 through to 2000, Vladimír Országh was attempting to crack the New York Islanders line-up, as he had a stint of 34 games in the NHL over those three years, tallying a total of five points (3 goals and 2 assists).
After becoming an unrestricted free agent after the 1999–2000 NHL season, Országh signed a contract with the Djurgårdens IF hockey team of the Swedish Elitserien, based in Stockholm.
The scouts of the Nashville Predators of the NHL noticed Országh's solid performance and signed him as a free agent the following season.
