Increased severe primary graft dysfunction in left ventricular assist device patients following united network for organ sharing allocation changes.

Incidence of severe PGD was similar in the overall cohort before and after the changes (10% vs. 15%, respectively, p = .3) and increased in the LVAD-bridged cohort (12% vs. 40%, respectively, p < .01). Secondary outcomes of readmission and survival were similar between all groups. Blood transfusion was predictive of severe PGD in multivariable modeling (OR 1.3 [1.11-1.59], p < .01).
