Predicted heart mass for size matching in obese heart transplant donors and recipients

INTRODUCTION: Predicted heart mass (PHM) was neither derived nor evaluated in an obese population. Our objective was to evaluate size mismatch using actual body weight or ideal body weight (IBW)-adjusted PHM on mortality and risk assessment. METHODS: We conducted a retrospective cohort study of adult recipients with BMI ≥30 kg/m² or recipients of donors with BMI≥30 kg/m² from the ISHLT registry. We used multivariable Cox proportional hazard …
