Cardiology Sites Taking Notice of the Radial
Approach to Angioplasty and Stenting (PCI)
Two
months ago, I
wrote about a poll on theheart.org, which asked the
question: "Should
radial access become the default choice for PCI?" Well,
as of today, the poll is still on their home
page. Evidently
radial access is a popular enough topic to warrant two whole months
of display.
This is interesting on several levels: one, this
poll has been posted and open for voting on theheart.org considerably
longer than previous polls; two, as of this morning (see graphic
above) over 500 votes have been tallied from healthcare professionals
who read theheart.org (this is a lot of votes for a typical poll
on their site!); and three, the vote is 50/50! -- and has been so over
the past couple of months, sometimes going up
to 52/48 in favor of radial.
This last point, the vote results, is even more interesting
because the most recent data from the NCDR
database shows that less than 3% of angioplasties done in the U.S.
are done
via the radial artery in the wrist; the mainstay of catheter-based
procedures in this country remains the femoral artery in the leg/groin.
(Not so around the world, where 50% or greater is the
norm. In fact those cardiologists who are proficient with the radial
technique tend to use it in 70-80% of their cases.)
So if less than 3% of PCIs are done via the wrist, why
is the vote 50/50? Is it because many cardiologists from outside
the U.S. have been voting? Or is it because many cardiologists
feel that radial should be the preferred access site -- but they
just don't practice it themselves? Or, more likely, aren't trained
in it?
For two years now, Angioplasty.Org has been offering
a special section on this technique, our Transradial
Access Center, offering information to both physicians and patients
about the advantages of the radial approach: less complications,
greater patient comfort, cost-effectiveness, etc. And we've also
been listing training opportunities, U.S. hospital centers
where radial is practiced, interviews with key cardiologists who
use it. And we've seen increasing interest in the radial approach
as a result.
In fact, today the weekly poll on another "professionals
only" cardiology site, CRTonline.org,
asks the question:
"How frequently should radial access for PCI
be used? Greater than 50%, between 20-50% or less than 20%."
Only 64 votes have been cast at present, and almost half
are saying "less than 20%", so it will be "interesting" to see how
this goes as the week progresses.
So...to you radialists out there, go
vote!!
Late Update: Alas! theheart.org has taken down its
poll -- glad I got a screenshot of the final tally.
Later Update: The poll at theheart.org --
is back online!
