Some Doctors Reluctant To Deactivate LVADs

–LVAD deactivation is not euthanasia or physician-assisted suicide.

Left ventricular assist devices (LVADs) are used increasingly as destination therapy instead of as a temporary bridge until a donor heart becomes available for transplantation. Now patients, their families, and their caregivers are forced to confront the extremely difficult question of when and how to turn off these devices at the end of life.

“In the United States, the ethical and legal principles of LVAD deactivation are well-established,” write Colleen K. McIlvennan (University of Colorado) and colleagues in a paper published in the Journal of Cardiac Failure. “An LVAD is considered a life support treatment, not a replacement treatment. Therefore, patients who have decision-making capacity or their surrogates may request deactivation of the life support treatment—in this case, an LVAD—when it is considered no longer effective or is believed to be more burdensome than beneficial.”

But the new paper offers evidence that some clinicians view “the act of LVAD deactivation as euthanasia or physician-assisted suicide.” In cases where clinicians don’t agree with the decision to deactivate the LVAD the authors wrote that “it is the clinician’s professional responsibility to transfer care to someone who can carry out the patient’s wishes.”

The study found that cardiologists and hospice and palliative medicine clinicians (HPMs) appear to have divergent views about LVAD deactivation. The findings raise important questions about how and whether medical professionals are prepared to deal with a fundamentally disruptive technology like the LVAD. However, the specific findings should not by any means be taken as definitive, since the study has important limitations. The paper is based on a survey the authors administered to cardiologists and HPM clinicians. But they only received responses from 440 out of 7,168 people who were invited to participate. The results then should not be considered representative of either group, but suggest areas of concern requiring further research.

Among the key findings:

  • 42% of cardiologists and 57% of HPMs had experience with a patient at the end of life who had requested LVAD deactivation.
  • 26% of cardiologists and 92% of HPMs “felt comfortable ordering the LVAD deactivation”
  • 26% of cardiologists and 59% of clinicians said they would be “comfortable” personally turning off the device.
  • 17% of cardiologists and 3% of HPMs said they had refused a request to turn off an LVAD.
  • 74% of cardiologists and 42% of HPMs thought a physician should be present at the time of device inactivation.
  • 60% of cardiologists and 2% of HPMs believe a patient must be “imminently dying” for inactivation to be considered.
  • 57% of cardiologists and 88% of HPMs thought that requests to deactivate the device should be honored in patients who were not near death.

A report last year from the same group found that LVAD patients and their caregivers suffer from an extraordinary amount of confusion and uncertainty near the end of life. Together, the two papers highlight that solving the difficult technical and medical issues associated with a new technology like the LVAD is only the beginning, since these technologies may result in unprecedented challenges. It is relatively easy to imagine the benefits created by a life-saving technology like an LVAD; it is far more difficult to imagine the unintended consequences of such a technology, such as the ethical issues involved in turning a life-sustaining device off.

    Glad to see this topic garner attention here. Advances in mechanical circulatory support offer tremendous possibilities that previously did not exist for patients dying from heart failure, but such technologies also create challenges. We need to pay attention to really tough issues like deactivation as we push forward to realize the opportunities that LVADs create.

  2. Who are your two “we”s, Mr Allen?

  3. I have wondered about this. I had a recent remote alarm and replacement situation and the sheer panic that ran through me was terrifying. If my system fails and I can’t get help what should I expect? Am I just going to fall over dead? Am I going to experience pain? I expect the panic and anxiety. I’ve felt that numerous times during my years as a heart patient. Dying in a hospital bed doesn’t scare me. What scares me is having the system fail and having to deal with an emergency issue that won’t allow me to say goodbye.
