This article presents how Conavi combined
the two standard intravascular imaging modalities
into one - the Novasight Hybrid™
System, the first and only intravascular imaging
system to combine co-registered
IVUS and OCT in a single system.
What's the Difference?
When it comes to the two cardiac imagExample
of side-by-side hybrid IVUS OCT image.
Society of Cardiology in August 2023, the
use of intravascular imaging dramatically
reduced instances of cardiac death (46 percent
reduction), target vessel MI (20 percent),
stent thrombosis (52 percent), and
reintervention (29 percent). Yet which imaging
fits best and what are the choices?
Traditionally, physicians have had to
choose between one of two modalities -
intravascular ultrasound (IVUS) or optical
coherence tomography (OCT). While
there are advantages and disadvantages to
both, cardiologists had to decide between
one or the other when performing coronary
interventions. That's where Conavi
came in, with a new and different idea.
ing options, IVUS has been the more commonly
used option, with over 70 percent of
cardiologists choosing this method when
selecting an imaging device. IVUS' depth
penetration is far superior to OCT, making
it the optimal choice for larger vessels such
as the left main and ostial lesions. IVUS
gives a better overall view of the artery and
plaque burden and eliminates the need to
use contrast to evaluate imaging results.
OCT, on the other hand, provides a
much clearer view of the affected vessel
than IVUS. OCT images can reach up to
10 times the resolution of IVUS. This
advantage makes OCT an ideal solution
for post-stent implantation evaluation
and assessment.
The obvious predicament is the tradeoffs
both require. With IVUS, the inferior
