She also decided to train in pediatric cardiology and moved to Toronto to study at the Hospital for Sick Children. As pediatric transplantation became more popular, While serving in this role, she pioneered the procedure to successfully transplant a heart from someone with one blood type into a baby with a different blood type. West's first ABO-incompatible heart transplant was on a baby named Caleb with type o blood. She conducted the transplant on the theory that a newborn's immune system was so immature, it had not yet developed the antibodies to attack the foreign heart. Due to her overall research and transplant success, West was recognized by Alberta Venture as one of the province's 50 Most Influential People in 2014. In the same year, West was also named to a three-year term on the Governing Council of the Canadian Institutes of Health Research.
