Background: The UK Department of Health funds ventricular assist device (VAD) implantation as a bridge to
transplantation (BTT) at three centers. The cost-effectiveness of this program has not been
established.
Methods: All 70 VAD implants for BTT and a consecutive cohort of 71 inotrope-dependent transplant
candidates, between April 2002 and December 2004, were prospectively monitored for survival,
transplantation, quality of life and resource use. Costs and quality-adjusted life-years were estimated
for these groups, and for a hypothetical scenario in which VAD patients would die within 30 days
in the absence of the program.
Results: Mean quality-adjusted life-years for a VAD patient was 3.27 at a lifetime cost of £173,841
(US$316,078). The majority of the cost was attributable to the VAD implant (£63,830, US$116,056)
and the initial hospital stay in the ITU and ward (£14,500, US$26,364). Inotrope-dependent
transplant candidates had mean quality-adjusted life-years of 4.99 at a lifetime cost of £130,905
(US$238,011). The worst clinical scenario resulted in a lifetime cost of £14,400 (US$26,182), based
on 1 month in the ICU (mean 15 days). These figures were robust to a range of plausible
assumptions.
Conclusions: A lifetime model based on current UK practice demonstrates that BTT VAD patients had significant
quality-adjusted life-years, but treatment was expensive when compared with the worst clinical
scenario. If device technology improves, costs are reduced, or referral practice changes, results
should be re-assessed. J Heart Lung Transplant 2006;25:1336 – 43. Copyright © 2006 by the

Heart transplantation is widely accepted as the most
effective surgical treatment for severe heart failure,
with 1-, 5- and 10-year post-transplant survival of 81%,
68% and 48%, respectively,
1
and quality of life compa-
rable to age- and gender-matched norms.

However,
there has been a steady decline in donor hearts over
time

and alternatives to transplantation are required.

A centrally funded program within the NHS was
established in 2002 to provide ventricular assist devices
(VADs) in three centers in the UK (the Freeman,
Harefield and Papworth Hospitals) with the intention of
bridge to transplant. The prospective Evaluation of
Ventricular Assist Device Program UK (EVAD-UK) study
was set up to evaluate the service and focused on
clinical/cost-effectiveness.
Evaluating low volume, high cost, but potentially
life-saving surgical interventions is difficult because
randomized, controlled trials (RCTs) of sufficient size
are often not feasible.

However, evaluation of VADs is
important because of its physical and psychologic inva-
siveness, and its high cost. Although EVAD-UK could
not provide formal trial data it did provide prospective,
systematically collected data on a multi-center cohort of
patients receiving a VAD and on concurrent inotrope-
dependent transplant candidates.
METHODS
All 70 patients implanted with VADs in the UK Govern-
ment–funded program between April 2002 and Decem-
ber 2004 were included. Devices used were the Heart-
Mate VE (n = 14), Thoratec (PVAD and IVAD, n = 42),
Jarvik 2000 (n = 13) and HeartMate II (n = 1). Patients
