Figure 3. Survival of heart transplant recipients before and after implementation of the new heart allocation policy by treatment type.
Recipients who were treated with ECMO before transplant (Panel A) experienced significantly increased 1-year survival in the post-policy cohort (69.3% [59.6%–80.6%] pre-policy vs. 87.2% [81.8%–93.0%] post-policy, log-rank P < 0.001). Recipients who were treated with IABP before transplant (Panel B) showed no significant difference in 1-year survival (92.1% [90.0%–94.3%] pre-policy vs. 91.1% [89.1%–93.2%] post-policy, log-rank P = 0.6). Recipients who were treated with mechanical ventilation before transplant (Panel C) experienced significantly increased 1-year survival in the post-policy cohort (68.2% [57.8%–80.4%] pre-policy vs. 82.9% [74.5%–92.2%] post-policy, log-rank P = 0.03). Recipients who were treated with durable LVAD before transplant (Panel D) showed no significant difference in 1-year survival (91.5% [90.6%–92.4%] pre-policy vs. 90.4% [88.5%–92.4%] post-policy, log-rank P = 0.3).
