When Dr. Ignacio Chávez founded Mexico’s Instituto Nacional de Cardiología in the early 1940s, he looked to the Incarnate Word Sisters to develop the hospital’s nursing department. He made a wise choice: Sr. Alacoque Cerisola (1897–1997), a petite Sister with exceptional organizational skills, developed procedures and standardized treatment that improved nursing not just at the Instituto de Cardiología but throughout Mexico.
