HealthDay News — The first case of computed tomography-guided percutaneous revascularization of coronary occlusion in man using a wearable, hands-free computer with a head-mounted display has been described. The report was published online November 19 in the Canadian Journal of Cardiology.

Maksymilian P. Opolski, MD, from the Institute of Cardiology in Warsaw, Poland, and colleagues described the first case of successful computed tomography-guided percutaneous revascularization of a chronically occluded right coronary artery in a 49-year-old male patient. The case involved novel application of a wearable hands-free computer with a head-mounted display, which was worn by interventional cardiologists in the catheterization laboratory.

The researchers noted that the operators could clearly visualize the distal coronary vessel with projection of 3-dimensional computed tomographic reconstructions onto the screen of virtual reality glass. Furthermore, they were able to verify the direction of advancement of the guide wire relative to the occluded vessel segment course.

“This case demonstrates the novel application of wearable computers for display of computed tomography angiography data sets in the catheterization laboratory that can be used for better planning and guidance of interventional procedures,” the authors wrote. “We believe wearable computers have a great potential to optimize percutaneous revascularization, and thus favorably affect interventional cardiologists in their daily clinical activities.”
