Adapted from Lynne Warner Stevenson
If we put an ICD in 100 patients with heart
disease like y
yours,
over the next 5 years we would expect:
• 30 patients will die
anyway
• 7-8 p
patients will be
saved by the ICD
• 10-20 would have a
shock they don’t need
• 5-15 would have other
complications
• The rest of patients will
not experience their
devices at all
Some patients will request to have the device

• VAD specific issues
Recap
• Cardiac devices definitely glitter, but
there ARE ethical dilemmas, especially

• Cardiac advance directives “are golden”
but complicated and require
multidisciplinary input
• Reused pacemakers are worth their

Feasibility of Device Acquisition
with Adequate Battery Life for
Potential Reuse in Underserved
Nations

• 2172 devices donated
• 10% with ≥75% battery life or 4 years
• Average time since implantation was
2 1±1 0 years
2.1±1.0
Caregivers
• Majority of VAD patients traditionally men,
but with smaller devices entering the
market more women expected to benefit
from this technology
• Traumatic spinal cord injury patients’
relationships do not fare as well when
patient is woman and caregiver is man
• Will this translate to VAD patients as well?
Bridge vs. Destination
Caregivers
• The few small studies that do exist
suggest

that p
partners/caregivers

patients experience significant

distress
• This is often counterbalanced by feelings
of pride and hope in caregivers of bridge
patients (has not yet been studied
specifically in Destination Therapy)

Return all devices
to manufacturers!
Competing Interests
• All devices with inadequate battery life
sent to manufacturers
• Increased return from
donationsincrease rate of return to
manufacturers
