MELD = 3.78*ln(bili) + 11.2*ln(INR) + 9.57*ln(Cr) + 6.43. MELD-Na = MELD + 1.32*(140-Na) - 0.168*MELD*(140-Na). Min input 1.0, Cr capped 4.0 mg/dL.

PVR in transplant: PVR >3 Wood units (240 dynes·s·cm⁻⁵) is associated with increased post-heart-transplant right heart failure risk. Reversibility testing with vasodilators is used to distinguish fixed from reactive pulmonary hypertension. PVR >5 Wood units that is irreversible is generally a contraindication to heart transplantation.
PVR (Wood units) = (mPAP − PCWP) / CO. PVR (dynes) = PVR(Wu) × 80. BSA = √(Ht(cm) × Wt(kg) / 3600) [Mosteller]. CI = CO / BSA.

GGT insight: GGT is uniquely included in ET-DRI (not in US DRI). For each 100 IU/L increase in GGT, ET-DRI rises by ~0.06. Particularly informative for DCD donors where hepatic stress is common. Review GGT alongside haemodynamic support requirements.
ET-DRI = exp(0.960*(age+COD+0.01*(CIT-8)+share) + 0.411*DCD + 0.422*split + 0.06*(GGT-50)/100 + 0.180*rescue). Reference: trauma, DBD, whole, local, CIT 8h, GGT 50, age under 40.

Complementary use: A young donor (ET-DRI 1.1) offered to a MELD-40 recipient carries very different risk than the same donor offered to a MELD-15 recipient. D-MELD captures this. Threshold: D-MELD 1600+ is associated with significantly worse 1-year graft survival.
D-MELD = donor age x recipient MELD. Below 1200: low risk. 1200-1599: intermediate. 1600+: high risk. Halldorson JB et al., Liver Transpl 2009;15:1279.

Sex mismatch insight: A female donor offered to a male recipient with matched body weights will almost always have a PHM ratio below 0.86 - the critical mortality threshold - because female hearts are 15-20% smaller at equivalent height/weight. Weight ratio alone misses this entirely. Always calculate PHM for sex-mismatched offers.
LV = a*H^0.54*W^0.61 (a=8.25M/6.82F). RV = a*Age^-0.32*H^1.125*W^0.315 (a=11.25M/10.59F). PHM ratio <0.86: HR 1.34 for 1-year mortality. ISHLT 2024: Class IIa, Level C. Kransdorf EP et al., JHLT 2019;38:156.

IPF caution: In restrictive disease the actual thoracic cavity can be 30-40% smaller than pTLC predicts. A matched ratio may represent functional oversizing. Most centres prefer donor pTLC at or below recipient pTLC for IPF. Consider CT chest volume assessment in borderline cases.
pTLC (men) = 7.99*H(m)-7.08. pTLC (women) = 6.60*H(m)-5.79. ISHLT bilateral target 0.75-1.25. Higher ratio (up to ~1.3) associated with improved survival and lower BOS risk. Eberlein M et al., AJRCCM 2013.

Heart transplantation: Total ischaemia above 4h is an independent risk factor for primary graft dysfunction and 30-day mortality. CIT is the coordinator concern - can I get this organ there in time? Total ischaemia is the surgeon concern - how long until reperfusion? Both should be estimated before accepting a heart offer.

Heart EGD — 2024 ISHLT Classification (10-year update)
Revised terminology and simplified severity grading replacing PGD. Inotrope score eliminated. Both LVEF ≤40% and haemodynamic compromise now required for LV classification. Severe EGD-LV sub-typed by presentation timing.
Kobashigawa et al., JHLT 2026 · 2024 Prague Consensus Conference
Informational use only. Standalone manual reference tool. Values are not stored. Not intended to guide clinical decision-making.
Key changes from 2014: PGD → EGD (Early Graft Dysfunction, <24h). New sEGD category (24–72h). Mild/Moderate/Severe → Non-Severe / Severe only. Inotrope score removed. LVEF ≤40% now required alongside haemodynamic compromise. Severe EGD-LV sub-classified: immediate (failed wean from CPB) vs delayed (after weaning). New RV echo criteria: RVEF ≤35% and/or TAPSE <1.6 cm.
Important change regarding ECMO: Under the 2024 classification, VA-ECMO alone does not qualify as Severe EGD-LV if LVEF is above 40%. LVEF ≤40% and haemodynamic compromise are both required before MCS is considered. The rationale given was that increasingly aggressive and prophylactic ECMO use — including continuation of pre-transplant ECMO without clinical indication — was inflating severe PGD rates. Patients on ECMO with preserved ventricular function should be evaluated for vasoplegia or institutional ECMO policy as the primary driver. This differs substantially from the 2014 criteria where ECMO immediately classified as Severe PGD regardless of echo findings.
Timing:
Left Ventricular (EGD-LV)
Right Ventricular (EGD-RV)
Classification note: EGD is a retrospective severity label for registry reporting and audit. If a known cause is identified (surgical, pulmonary hypertension, immunological, etc.) the classification is Secondary Graft Dysfunction (SGD), not EGD. The tool asks this as its final step.

< 200Severe hypoxaemia

Yes
No
BOS risk: All grades at all time points independently increase bronchiolitis obliterans syndrome (CLAD/BOS) risk. T48–T72 grades are most prognostically significant for mortality. 30-day mortality for Grade 3: ~36–50%.
P/F ideally on PEEP 5 cmH₂O at FiO₂ 1.0 on mechanical ventilation. SpO₂/FiO₂ cutoffs: 235 and 315. Vasodilators (NO, epoprostenol) do not change grade. ECLS without bilateral infiltrates = ungradable. Exclude cardiogenic oedema, anastomotic complications, infection, aspiration.
Liver — Post-transplant — Retrospective classification
Liver Early Allograft Dysfunction (EAD)
Any single criterion met = EAD positive. Three criteria reflect hepatocellular injury (transaminases), synthetic function (INR), and excretory function (bilirubin).
Olthoff et al., Liver Transpl 2010;16:943
Informational use only. Standalone manual reference tool. Values are not stored. Not intended to guide clinical decision-making.
Criterion 1 — Peak transaminase, days 1–7
Peak AST or ALT > 2000 IU/L within first 7 days
Not met
Criterion 2 — INR on day 7
INR on postoperative day 71.2
Threshold: ≥1.6 · Reflects synthetic graft function
Criterion 3 — Bilirubin on day 7
Units:
Total bilirubin on day 72.0 mg/dL
Threshold: ≥10 mg/dL (171 µmol/L) · Strongest single predictor of mortality
EAD criteria met

Bilirubin and INR dominate: Transaminase-only EAD (AST/ALT criterion, normal bilirubin and INR) does not independently predict mortality in most analyses. Bilirubin ≥10 mg/dL and INR ≥1.6 on day 7 are the clinically meaningful thresholds. When both are met, early retransplant evaluation is warranted.
Olthoff KM et al. Liver Transpl 2010;16:943. EAD incidence 23.2%. Mortality 18.8% EAD vs 1.8% non-EAD (RR 10.7). Graft loss 26.1% vs 3.5%.
Kidney — Post-transplant — Retrospective classification
Kidney Early Graft Function — IGF / DGF / PNF
Three distinct post-transplant functional states reflecting the severity of ischaemia-reperfusion injury and early allograft performance.
UNOS/OPTN definition · Halloran et al. · Irish et al.
Informational use only. Standalone manual reference tool. Values are not stored. Not intended to guide clinical decision-making.
Immediate Graft Function (IGF)
Creatinine falls ≥10% per day on each of the first 3 postoperative days. No dialysis required. Minimal ischaemia-reperfusion injury.
Delayed Graft Function (DGF)
Need for dialysis within the first 7 days post-transplant (UNOS definition). Most widely used clinical and registry definition. Incidence 20–50% depending on donor type.
Primary Non-Function (PNF)
Permanent graft failure — the kidney never functions following transplantation, without immunological, surgical, or urological cause. Requires retransplant listing.
DGF vs slow graft function (SGF): Some centres use a third category — SGF — defined as failure of creatinine to fall below 3 mg/dL by day 5 without requiring dialysis. Not a universally adopted registry definition but captures an intermediate group. The UNOS dialysis-based DGF definition remains the standard for registry reporting. DGF incidence is significantly higher after DCD donation (~40–50%) than DBD (~20–25%).
UNOS dialysis-based DGF definition. Irish WD et al. Transplantation 2010. Halloran PF et al. Am J Kidney Dis 1988. DGF incidence: ~20–25% DBD, ~40–50% DCD. PNF incidence: ~1–5%.
