Guidant ICD
I another bizarre corporate twist: I was held hostage at Mease
Countryside Hospital in Clearwater, Florida a couple months ago. After
checking into the Sleep Disorders Center, a technician noticed something
"funky" in my EKG just after the testing began. I was rushed a few
hundred feet away to the Emergency Room where I underwent several hours
of blood tests, X-rays, and EKG's. THose did not show anything wrong.
But the doctor on duty did not want to release me, until after my
Guidant ICD could be interrogated.
Guess what? That did not happen for three (3!) days - so I sat there for
half a week taking up a bed in CICU as my insurance company shelled out
thousands of dollars for me to read and watch television! Turns out Bay
Care, the megamedical company that operates seven hospitals in this part
of Florida has signed an exclusivity deal with Medtronic - shutting out
Guidant and other device makers. Medtronic is supposed to be on call to
handle things such as in-hospital interrogations of non-Medtronic units
as well and turning those devices off before surgery and back on after
we come out of the recovery room.
I called Guidant, and pleaded for help. But because there is no longer a
demand for their products around here... they had to lay off many of
their field technicians and had no one they could send. And apparently
no Medtronic techs were on duty or even on call in this area, so I
waited and waited and waited until Guidant had a tech drive from Fort
Myers to Clearwater to test my device - showing it, too, was just fine.
The funky EKG that caused all the concern? Probably due to a loose
sensor wire.
After that episode, a Guidant executive I've known for ten years called
and chatted. He says a Bay Care Vice President and an
Electrophysiologist in Clearwater ramrodded the excusivity deal through
the approval process - after which both got six figure "consultation
fees." There's a hell of a story here, but sadly it's only one of a
zillions reasons our health care costs are running out of control.

Needless to say, when my EP told me he wanted me to undergo one of the
dreaded NIPS Tests... having it done at Mease Countryside was not an
option. It meant driving an hour north to have the procedure done at the
HCA Bayonet Point Medical Center in Hudson. That was done two weeks ago
today. It was a flawless exercise and the hospital folks up there are
among the most professional I have encountered in the dozen years since
my heart attack.
A friend of mine, a producer at the NBC TV station in Tampa, went along
to take pictures of the whole thing. He shot it using my HD videocam and
got some great stuff. The worse part of the process was having my chest
shaved for the external defibrillator adhesive pads. I did not like that
at all. That's on tape. Also recorded: Me chanting (while unconscious) a
tune sung by monks in a Tibetan monastery! I hope to get the tape edited
into a mini-documentary next week and turn it into a video podcast that
can be downloaded here. I will likely offer it for free, but hope people
who download it will make a small donation

In the distant past, Zapper readers were often paralyzed by fearwhen
told they were to undergo a NIPS test. But, when we recently asked,
"What scares you THE MOST about having an ICD?" in a Zapper BBS poll...
the NIPS test was only mentioned once! Of the 73 people who actually
voted...
1.
GETTING ZAPPED remains the top fear, earning 54% of the tallies.
2.
DEVICE FAILURE came in second with 27%
3.
OTHER was the third with 15% of the votes..
4.
NIPS test tied for fourth with ALTERING MY LIFESTYLE
Comments by OTHER voters provides some interesting insights. Those
choosing that option mentioned magnests, driving, kids getting
implanted, passing out while doing something needing a high level of
attention and hurting someone, and getting zapped in public. Thanks to
ALL who took the time to take part in the unscientific survey. With more
than 1400 reading the postings... I hope more folks will come back and
vote.
Defibrillator Lead Report Misleads
It didn't take long for the media to chew up this week's report on the
high failure rate of old defibrillator leads published in Circulation
from a single center registry from Germany today. What's better than to
scare the heck out of patients? I mean, fear sells, doesn't it?
For those of you who haven't seen it yet, doctors from Germany decided
to look back at their last 990 consecutive defibrillator lead implants
between 1992 and 2005. They found 148 (15%) of defibrillator leads
failed during follow-up and required replacement. They found that annual
failure rates increased over time, peaking at 20% in 10-year-old leads.
But before you go out an insist that your defibrillator be removed,
let's look at a few facts from the very same article:
* 15% of the leads had problems, 85% of them did just fine.
* No patent died as a result of ICD lead failure
* Older lead materials that have since been show to have high failure
rates are no longer used, but included in this report
* The authors performed 95% of their implants using a subclavian
approach, an approach they freely admit is prone to an unusually high
level of lead "crush" as the lead passes between the first rib and
clavicle. Like a coat-hanger repetitively bent, leads implanted by this
approach are subject to a higher failure rate.
But the authors do make several valuable points: (1) defibrillators and
their leads need constant monitoring, even after they are implanted and
(2) in patients implanted for "primary prevention" of a cardiac
arrhythmia (that is, they've never had an arrhythmia before the device
is implanted), consideration of device failure over the lifetime of the
patient should be considered when recommending a device for
implantation.
It is important to note that the Heart Rhythm Society has been aware
that these devices can be subject to malfunction on occasion. As such
they have recommended that implantable cardiac defibrillators (ICDs) be
evaluated every three months by a qualified physician. Further, most of
the ICD manufacturers are developing wireless telemetry systems that can
check these devices even as often as daily to assure their reliability.
Furthermore, companies have migrated away from the form of polyurethane
that can degrade when exposed to metal oxides (as occurred in leads
manufactured before 1997). The fact that these older leads were included
in the analysis serves to make the data more sensational and
press-ready.
I would suggest that people evaluate the performance data maintained by
each of the companies and published on-line. Boston Scientific's
(formerly Guidant) performance data on their devices can be found here,
Medtronic's here, St. Jude's here and Biotronik's can be found here.
These data suggest current failure rates for most ICD's is approximately
10% after 10 years, fully one-half of that described by the authors in
the above article. Certainly, this number is not perfect, but helps keep
a reasonable perspective on defibrillator lead reliability, and reflects
the world-wide experience of patient's with a particular lead or device
system, and may be a more accurate reflection of lead trends across
multiple centers and operators.
