- W2024009725 abstract "BackgroundPrimary graft failure (PGF) is the leading cause of early heart transplantation (HT) mortality. Our aim was to analyze PGF currently and explore the ability of a dedicated score for PGF risk stratification.MethodsAfter applying a dedicated PGF definition, we analyzed its incidence, mortality, and associated factors in a multicenter cohort of 857 HTs performed in 2006 to 2009. We used the following criteria: recipient right (R) atrial pressure ≥ 10 mm Hg; age (A) ≥ 60 years; diabetes (D) mellitus, and inotrope (I) dependence; donor age (A) ≥ 30 years, and length (L) of ischemia ≥ 240 minutes to calculate the RADIAL score for PGF risk prediction.ResultsPGF incidence was 22%. The right ventricle was almost always affected, alone (45%) or as part of biventricular failure (47%). Mechanical circulatory support was used in 55%. Mortality attributable to PGF was 53% and extended through the third month after HT, but thereafter, PGF had little influence in long-term outcome. The RADIAL score was higher in PGF patients (2.78 ± 1.1 vs 2.42 ± 1.1, p = 0.001) and stratified 3 groups with incremental PGF incidence: low risk (12.1%), intermediate risk (19.4%), and high risk (27.5%, p = 0.001).ConclusionsPGF had a strong impact, with an incidence of 22% and a mortality exceeding 50% that extends through the third post-HT month. The RADIAL score classified patients into 3 groups with incremental risk for PGF and may be useful for its prevention and early therapy.
