She was the third wife of President Juan Perón. During her husband's third term as president from 1973 to 1974, Isabel served as both vice president and First Lady. Following her husband's death in office in 1974, Isabel served as president of Argentina from 1 July 1974 to 24 March 1976, when the military took over the government and placed her under house arrest for five years, before exiling her to Spain in 1981.

One of her daughters, Laura Estela Carlotto, was kidnapped and missing while pregnant in Buenos Aires, in late 1977. Through stories, she could ascertain that her daughter had given birth to a boy, and that her grandson was appropriated and his identity changed. She searched for him for nearly 36 years, until, on August 5, 2014, after a DNA check voluntarily made by the person concerned, her grandson was identified, and became the 114th in the list of recovered grandchildren.
