Contacts- Christoph Knosalla
- Sabine Hübler
Emails Inclusion criteria- Patient (male or female) eligible for heart transplantation and accepted in T Status (transplantable) on the waiting list
Age 18 to 65 years
Signed informed consent
>30% 1-year mortality with the Seattle Heart Failure Model (SHFM) or at least three of the following criteria (a) to (f):
cardiac index (CI) <2.5 l/min/m²
pulmonary capillary wedge pressure >15 mmHg
maximal oxygen uptake (VO2max) ≤10.0 ml/kg/min or ≤12.0 ml/kg/min in patients intolerant of a ß-blocker
ratio of minute ventilation (VE) to carbon dioxide (VCO2) production (VE/VCO2) slope of >35
at least two hospitalizations for heart failure within the previous 12 months
documented increase of brain natriuretic peptide (BNP) or NTproBNP levels despite optimal medical therapy
Exclusion criteria- Listing for transplantation of other organs in addition to heart
Previous cardiac surgeries (other than pacemaker or ICD surgeries)
Contraindications to assist device implantation (e.g. mechanical aortic valve
- aortic insufficiency)
Contraindications to anticoagulation
Expected need for a right ventricular assist device/biventricular support expected (e.g. due to tricuspid valve insufficiency grade 3+
- right ventricular ratio short/long axis ≥0.6
- ratio of right to left ventricular end-diastolic diameter (RVEDD/LVEDD) >0.72
- restrictive cardiomyopathy)
Presence of catecholamine support or intra-aortic balloon counterpulsation (IABP)
Overt infections
Fixed pulmonary hypertension (i.e. pulmonary arterial pressure (PAP) >60 mmHg and mean transpulmonary gradient (TPG) >15 mmHg or pulmonary vascular resistance (PVR) >6 Wood units despite optimal medical treatment)
Renal insufficiency (glomerular filtration rate (GFR) <30ml/min or need for hemodialysis or hemofiltration)
Significant coagulopathies
Systemic lupus erythematosus
- sarcoid
- or amyloidosis that has multisystem involvement and is still active
Drug abuse and/or alcohol abuse
Incompliance
Elevated panel reactivity levels of >50 %
Pregnancy or breast feeding in women
Participation in other investigational trials
