This foundation was begun in 1981 by the Princess Mother. Vadhana became its patron on 15 June 1984. She added some of her personal property to her mother's fund and provided personal advice, thus developing its activities. It helps many sick children, especially from poor families, to be cured and treated by professional cardiac doctors, using mechanical heart valve replacement, heart pacemaker, balloon catheter, and surgery without prosthesis. Furthermore, this foundation disseminates knowledge of cardiac diseases to doctors, nurses, and the public. It also provides funds for pediatricians to study cardiac diseases in children either in Thailand or abroad.
