The Servier Virtual Cardiac Centre Allows Doctors to See Inside the Heart
When it comes to looking at a patient’s insides, doctors have long been able to use radiation and sound to “see” bones, muscles and organs. X-rays, MRI and ultrasound continue to provide doctors with reliable, two-dimensional images.
“We have the technical base to develop new knowledge right here in Edmonton that will be used around the world,”
There’s plenty of innovation that this lab has embraced in its very short existence. Walk in, and you’ll see a couple of large screens and a bank of smaller computers. An image of a patient’s heart is called up on the largest screen, and Dr. Noga hands me a pair of 3D glasses. I put them on, and now the heart is floating in front of my eyes.
“It’s like comparing a 3D movie to a flat-screen TV,” she says.
But it’s not just about the doctors. A patient can view his or her own organs. Instead of receiving a diagnosis filled with Latin and complex medical terms, a person can look at his or her own heart and be shown what’s wrong.
“It helps the patient understand what’s happening in their own body,” says Noga. “They’ll better understand the surgery that’s coming up, they’ll understand what’s going to happen to them. And patients are all curious about what they look like on the inside.”
She shows a new example on the screen; with the glasses on, we see a 3D image of a heart valve. It opens, but there’s a gap when it’s supposed to close. She explains that this is an image from an infant who had a heart defect — a leaky valve. Without any medical training, I can see that the valve doesn’t close properly. Now, imagine the nervous parents of this child being shown this image; they’ll know exactly what the doctors have to do, and why.
This also helps with patients who might not be taking their medications or following their diets. We can be told that we have a heart condition, but we’ll feel fine and think that it’s OK to cheat on our diets or skip our pills. Using the 3D image, the patients can see that there are issues with their health that need to be constantly addressed. It works a lot better than a verbal diagnosis in passing on the message. As Noga says, when a patient sees a scan, it’s a “eureka moment.” But there’s even newer technology available.
I’m handed a wand as an image is loaded on another computer screen. Through the glasses, I can see a beam of light extend from the wand, and using that as virtual “chopstick,” I can bring the heart closer to my eyes or turn it around. I’m given a headset with goggles attached, no different than the VR headsets you find at a Best Buy’s video-game section. I’m handed two controllers, one for each hand, that, well, feel exactly like I’m about to play the latest BioWare game. Using the triggers on the controllers, I can control the 3D image of the organ in front of me, I can even make cuts to it to look inside.
The images can be created by fusing ultrasound images together. And the images are so clear that doctors can possibly pick up things that might have been missed by traditional scans. It may be easier to see early signs of heart diseaseor cancer in high-risk candidates. And,of course, the earlier an abnormality is spotted, the easier it is to treat. “As technology advances, so do our tools,” says Noga. “The technology just keeps getting better and more affordable.” And that means, for cardiac patients at the Maz, even greater chances of recoveries and successful returns to their lives.
