In March, Héduit competed at the Birmingham World Cup, marking her international debut as a senior. She finished fourth behind Aliya Mustafina of Russia, Riley McCusker of the United States, and Thaís Fidélis of Brazil. In June, Héduit placed sixth at the French national championships, and went on to compete at the 2019 European Games in Minsk, Belarus. She finished 17th all-around in qualifications, but did not make the final due to the two-per-country rule. She missed the second half of the 2019 season due to an ankle injury for which she had surgery in August.
