Virtual reality (VR) has potential to revolutionize some aspects of medicine and
healthcare. Several medical specialties are already using it to train physicians
and assist diagnosis and it also has potential for treatment. A group of
cardiologists has now successfully used a VR device to guide the opening up
(revascularization) of a chronically blocked right coronary artery. Their report
is published in the Canadian Journal of Cardiology.

--------------------------------------------------------------------------------

Chronic total occlusion, a complete blockage of the coronary artery, sometimes
referred to as the "final frontier in interventional cardiology," represents a
major challenge for catheter-based percutaneous coronary intervention (PCI).
This sentiment is driven by the unpredictable procedural success rates related
to the difficulty of recanalizing chronic total occlusions with percutaneous
techniques as well as incomplete visualization of the occluded coronary arteries
by conventional coronary angiography radiology methods.

Consequently, there is substantial interest in using novel imaging methods for
preprocedural characterization of chronic total occlusion. Coronary computed
tomography angiography (CTA) is increasingly used to provide physicians with
guidance when performing PCI in this subset of lesions. The occluded coronary
segment and the distal vessel territory are often more clearly depicted using
coronary CTA than in invasive angiography. Of particular interest, the procedure
itself can be facilitated by projection of three-dimensional CTA data sets on
separate monitors in the catheterization laboratory, but this technique is
constrained by economic and technical factors.

Cardiologists from the Institute of Cardiology, Warsaw, Poland were able to
successfully restore blood flow in the occluded right coronary artery of a
49-year-old male patient assisted by CTA projections in a wearable VR device
based on Google Glass, with an optical head-mounted display. The display of
three-dimensional computed tomographic reconstructions in a mobile application
equipped with a hands-free voice recognition system and a zoom function,
developed specifically for this purpose by a team of physicists from the
Interdisciplinary Centre for Mathematical and Computational Modelling of the
University of Warsaw, enabled the physician-operators to clearly visualize the
distal coronary vessel and verify the direction of the guide wire advancement
relative to the course of the blocked vessel segment. The procedure was
completed successfully with implantation of two drug-eluting stents.

"This case demonstrates the novel application of wearable devices for display of
CTA data sets in the catheterization laboratory that can be used for better
planning and guidance of interventional procedures, and provides proof of
concept that wearable devices can improve operator comfort and procedure
efficiency in interventional cardiology," explained lead investigator
Maksymilian P. Opolski, MD, PhD, of the Department of Interventional Cardiology
and Angiology at the Institute of Cardiology, Warsaw, Poland.

The device used, Google Glass, consists of a wearable, hands-free computer with
an optical head-mounted display worn by interventional cardiologists in the
catheterization laboratory. The optical head-mounted display can display and
capture images and videos while interacting with the surrounding environment.
This display is an example of the concept of VR in which the user is
supplemented with additional information generated by the device.

"Mobile technology is easily accessible and offers an incremental opportunity to
expand the existing open platform for mobile applications, which might in turn
overcome the economic and capacity limitations of advanced angiography systems
with dedicated monitors for projection of CTA data sets," added Dr. Opolski.
"Furthermore, wearable devices might be potentially equipped with filter lenses
that provide protection against X-radiation. We believe wearable computers have
a great potential to optimize percutaneous revascularization, and thus favorably
affect interventional cardiologists in their daily clinical activities."
