The aim of the study is to assess whether, in patients who are listed for cardiac transplantation in transplantable (T) status, early implantation of a left ventricular assist device is superior to the current therapeutic strategy of medical heart failure therapy and assist device implantation only after serious deterioration of the patient's condition.
Heart transplantation is considered the gold-standard therapy for end-stage systolic heart failure but the shortage of donor hearts in Germany and other countries has led to widespread use of left ventricular assist devices (LVAD). Even on the transplant list, patients' condition often deteriorate due to worsening heart failure so that they need an LVAD as a bridge until transplantation. The high mortality (one in five patients on the waiting list dies within 1 year) reflects the severity of the disease. In comparison, technical progress has reduced the complication rate seen with assist devices and, according to recent data, mortality during LVAD support is low. Patient status prior to LVAD implantation is a strong indicator for postoperative outcome, i.e. patients in worse condition are more likely to develop complications. Thus, the comparison between the standard indication and early LVAD implantation (T-status) appears timely and clinically necessary.
The paucity of donor hearts necessitates the prospective evaluation of alternative treatment regimens. The aim of the study is to assess whether, in patients with end-stage heart failure awaiting cardiac transplantation, a strategy involving early LVAD implantation is superior to a strategy of conservative medical heart failure therapy and assist device implantation only after severe deterioration of heart failure.
The investigators expect to gain insights that will be trail-blazing for the future treatment of patients with heart failure on the transplantation waiting list, including aspects of their medical care. If the study hypotheses are confirmed, the treatment of these seriously ill patients could be, on the one hand, further optimized. On the other hand, positive economic effects are highly probable.
The results will form the basis of future guidelines for the treatment of this group of patients.
Thus the study will also make a contribution to solving the problem of the ever increasing number of patients on the waiting list as opposed to the decreasing willingness to donate organs for transplantation.
As a mean of quality control of the conducted study and to retrieve more data in this population all patients who fulfill the eligibility criteria of the study but do not consent to randomization are included in a standard treatment registry.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Early VAD implantation | Experimental | The experimental intervention is early implantation of a left ventricular assist device (early VAD). Patients randomized to early VAD implantation will obtain a VAD within 28 days after randomization. |
|
| Emergency VAD implantation | No Intervention | The control intervention is conservative heart failure treatment, with LVAD implantation in the case of worsening heart failure (emergency VAD). All patients randomized to the control intervention will be treated according to standard medical practice. In brief, these patients are closely monitored (scheduled regular visits to outpatient department depending on the patient's condition and at least every 6 months). If the condition worsens the patient may qualify for high urgency (HU) listing and/or for VAD implantation. |
