Effectiveness in Stenting
Aside
from stents themselves, there's a whole toolbox of devices and techniques
that are candidates for "comparative
effectiveness" in that they may be able to increase the success
of interventional procedures -- or even target patients who need these
procedures more accurately. As Volcano Corp.'s CEO Scott Huennekens
wrote in a recent
Washington Times op-ed piece:
The United States needs to focus on treating
the right patient at the right time with the right method to
lower health care costs, improve patient outcomes and foster
research and development.

Huennekens' piece was titled, "Obama
effectiveness proposal: a tool for finding faster, less expensive
medical solutions? "
and he details why he agrees with and supports President Obama's
decision to study "comparative effective research" -- primarily
because there are a number of ways that new technologies, many
of them (of course) manufactured by his company, will be useful
for interventional cardiology.
Among
them is intravascular ultrasound (IVUS) which shows
more accurate
information about stent placement and expansion than can be seen
on an angiogram. Last July Angioplasty.Org posted an article titled,
"Intravascular
Ultrasound (IVUS) May Reduce Drug-Eluting Stent Thrombosis by
a Third" showing the results of a study, led by Dr. Ron Waksman of
Washington Hospital Center.
Another is Fractional Flow Reserve (FFR) which can measure
whether or not a blockage seen to be significant on an angiogram
is in fact obstructing blood flow, and how much. The recently published
FAME study, detailed in our piece, "Better
Outcomes for Stents When Fractional Flow Reserve (FFR) is Used", showed
28% reduction in major cardiac events when FFR was used to determine
which blockages to stent and which to leave alone. Also one-third
less stents were used: more effective therapy and more cost-effective
too.
We continue to cover other areas where the effectiveness
of catheter-based therapy can be improved. Our Transradial
Access Center details the ways in which bleeding complications can
be reduced, just by changing the access site for diagnostic and interventional
procedures. And we're closely following the use of other imaging
modalities, like Cardiac CT angiography (CCTA) which shows promise
in eliminating a significant number of invasive diagnostic caths
by accurately ruling
out coronary disease -- and Optical Coherence Tomography (OCT) which
may help in determining stent strut coverage and whether it is safe
for the patient to stop taking antiplatelet drugs, such as Plavix.
Innovation in medicine may not only be cost-effective,
it may be profitable as well. In an
excerpt from The Wall Street Transcript's annual Medical Device
issue,
Matt Dolan of ROTH Capital Partners predicts that, counter to some
companies, Volcano is looking at a continued growth rate of 20%.
Very effective, indeed.
(By the way, the photo posted with Scott Huennekens' op-ed on the
Washington Times web site is NOT Huennekens, but Montana Senator
Max Baucus
-- go figure.... Huennekens is pictured correctly at the top of
this article.)
