Background Heart failure is a major public-health concern. Quality and dura
tion of life on maximum medical therapy are poor. The availability of donor
hearts is severely limited, therefore an alternative approach is necessary
. We have explored the use of a new type of left-ventricular assist device
intended as a long-term solution to end-stage heart failure.
Methods As part of a prospective clinical trial, we implanted the first per
manent Jarvik 2000 Heart-an intraventricular device with an innovative powe
r delivery system-into a 61-year-old man (New York Heart Association functi
onal class IV) with dilated cardiomyopathy. We assessed the effect of this
left-ventricular assist device on both native heart function and the sympto
ms and systemic characteristics of heart failure.
Findings The Jarvik 2000 Heart sustained the patient's circulation, and was
practical and user-friendly. After 6 weeks, exercise tolerance, myocardial
function, and endorgan function improved. Symptoms of heart failure have r
esolved, and continuous decreased pulse-pressure perfusion has had no adver
se effects in the short term. There has been no significant haemolysis and
no device-related complications. The skull-mounted pedestal is unobtrusive
and has healed well.
Conclusions The initial success of this procedure raises the possibility of
a new treatment for end-stage heart failure. In the longer term, its role
will be determined by mechanical reliability.
