GUARDIAN-Heart 2-Year Clinical Summary

Investigators found that 2-year post transplant survival in matched cohorts (from 89% to 95%, p=0.04) is superior in the SherpaPak cohort¹. This survival benefit is potentially due to reduced the incidence of severe PGD (from 11% vs 5.5%, p=0.01) and reduced need for mechanical circulatory support after transplant¹. The study concluded that Advanced hypothermic preservation of the donor heart should be strongly considered as an important factor contributing to a center’s post transplant and 2-year outcomes.¹
