Key result
Jarvik 2000 LVAD controls unremitting ventricular arrhythmia and normalizes cardiac output in a HF patient.
Why the study?
Refractory ventricular arrhythmias in chronic congestive heart failure can exacerbate heart failure and may require advanced mechanical support.
Does the Jarvik 2000 FlowMaker left ventricular assist device improve cardiac output and control refractory ventricular arrhythmias in a patient with chronic congestive heart failure?

Does the Jarvik 2000 FlowMaker left ventricular assist device improve cardiac output and control refractory ventricular arrhythmias in a patient with chronic congestive heart failure?
The Jarvik 2000 FlowMaker LVAD may be effective in normalizing cardiac output and controlling refractory ventricular arrhythmias in patients with chronic congestive heart failure.
May support Jarvik 2000 for refractory arrhythmia in HF; hypothesis-generating case report leaves open need for prospective trials.
Chronic congestive heart failure is not uncommonly associated with ventricular arrhythmias. In a small percentage of these cases, the arrhythmias may become refractory to medical therapy and exacerbate the patient's underlying heart failure. The authors report such a case, in which ventricular failure necessitated insertion of a Jarvik 2000 FlowMaker left ventricular assist device (Jarvik Heart Inc., New York, NY). In addition to normalizing the cardiac output, this axial-flow device controlled the previously unremitting ventricular arrhythmia.

Wadia et al. (2004) conducted a case report in Chronic congestive heart failure with refractory ventricular arrhythmias (n=1). Jarvik 2000 FlowMaker left ventricular assist device was evaluated on Control of ventricular arrhythmia and normalization of cardiac output. Insertion of a Jarvik 2000 FlowMaker left ventricular assist device normalized cardiac output and controlled previously unremitting ventricular arrhythmia in a patient with heart failure.
