Cardiac transplantation indication criteria

ICD, implantable cardioverter-defibrillator; NYHA, New York Heart Association; Vo2, oxygen consumption.
1. Accepted Heart Failure Survival Score (HFSS, Aaronson 19976) high risk
Peak Vo2 <10 ml/kg/min after reaching anaerobic threshold
NYHA class III/IV heart failure refractory to maximal medical treatment
Severely limiting ischaemia not amenable to interventional or surgical revascularisation
Recurrent symptomatic ventricular arrhythmias refractory to medical, ICD, and surgical treatment
2. Probable HFSS medium risk
Peak Vo2 <14 ml/kg/min and severe functional limitations
Instability of fluid status and renal function despite good compliance, daily weights, salt and fluid restriction and flexible diuretics
Recurrent unstable ischaemia not amenable to revascularisation
3. Inadequate HFSS low risk alone
Peak Vo2 >15–18 ml/kg/min without other indications
Left ventricular ejection fraction <20 % alone
History of NYHA class III/IV symptoms alone
History of ventricular arrhythmias alone
