A clinical study, conducted by Philips (Best, The Netherlands) and RealView Imaging, Ltd. (Yokneam, Israel) has shown the feasibility of using a special live three-dimensional (3D) holographic visualization and interaction technology to guide minimally invasive structural heart disease procedures.

In the pilot study that included eight patients and was performed in cooperation with the Schneider Children’s Medical Center (Petach Tikva, Israel), RealView’s innovative visualization technology was employed to show interactive, real-time 3D holographic images obtained by Philips’ interventional X-ray and cardiac ultrasound systems.

Physicians in the interventional team were able to view detailed dynamic 3D holographic images of the heart “floating in free space” during a minimally-invasive structural heart disease procedure, all the while viewing the patient’s heart on a 2D screen, without using special eyewear. The physicians were also able to influence the projected 3D heart structures by just touching the holographic volumes in front of them. The study’s findings revealed the potential of the technology to optimize the context and guidance of structural heart repairs.

“The holographic projections enabled me to intuitively understand and interrogate the 3D spatial anatomy of the patient’s heart, as well as to navigate and appreciate the device-tissue interaction during the procedure,” said pediatric cardiologist and director of the Institute of Pediatric Cardiology at Schneider Children’s Medical Center, Dr. Einat 3d heart

“The ability to reach into the image and apply markings on the soft tissue anatomy in the X-ray and 3D ultrasound images would be extremely useful for guidance of these complex procedures,” added pediatric cardiologist and director of the Cardiac Catheterization Laboratories at Schneider Children’s Medical Center, Dr. Elchanan Bruckheimer.

The findings of this one of a kind pilot study was presented by Bruckheimer at the 25th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium, held October 27-November 1, 2013, in San Francisco (CA, USA), and sponsored by the Cardiovascular Research Foundation.

“Our ultimate goal is to create the future of healthcare by delivering innovative solutions that enhance clinical capabilities and improve patient outcomes. By teaming up with partners that share our passion for innovation, we have been able to demonstrate the feasibility and potential value of the world’s first holographic visualization technology targeted at guiding minimally invasive cardiac procedures, said general manager of integrated clinical solutions and marketing for imaging systems at Philips Healthcare, Bert van Meurs.

Progress in image-guided treatment therapies for heart disease, from the opening of blocked coronary arteries to catheter ablation therapy for heart arrhythmias and catheter-based structural heart procedures (for example, heart valve replacements), have considerably raised the need for live 3D image guidance, to enhance present live 2D image guidance. Live X-ray and live 3D cardiac ultrasound imaging are usually used concurrently to guide minimally invasive structural heart repair procedures, with the ultrasound images supplying detailed insights into the heart’s soft tissue anatomy, and the X-ray imaging supplying visualization of catheters and heart implants.

“I see clear indications that 3D medical holography will play an important role in medical imaging in the near future. With the advancement of live 3D imaging and increasing clinical evidence of its value for a variety of procedures, we are convinced that our holographic technology will further enhance 3D imaging and, most importantly, improve patient care,” said CEO of RealView Imaging, Aviad Kaufman.

The technologic developments in the acquisition of live 3D images to guide minimally invasive procedures have also sparked the development of new ways to visualize the data.

Following the promising findings produced by this pilot study, Philips and RealView Imaging will continue to examine the clinical benefits of incorporating live 3D imaging and medical holography, both in interventional cardiology and in other clinical areas.
