CTO
1.1 CTO Chronic total occlusion (CTO) of one or more coronary vessels are relatively common findings in coronary angiography. One large-scale registry showed that up to 20% of patient with coronary artery disease had a CTO. (1) Compared to percutaneous coronary intervention (PCI) of non-occluded vessel, CTO PCI has a l...

CTO Proctoring
1.2 CTO Proctoring Several studies have showed a relationship between physician volume and outcomes of percutaneous coronary interventions (PCI) with better outcomes reported for high volume operators when compared with low volume operators.(3) Proctoring in medicine is related to better outcomes. Specifically, in CTO ...

Microsoft HoloLens in proctoring
1.3 Microsoft HoloLens in proctoring This study aims to evaluate the Microsoft HoloLens as a potential platform in proctoring and effective real time communication between PCI operators located at different geographical locations. The proctor and the local operator interact using a head mounted mixed reality (MR) displ...

Mixed reality in medicine
1.4 Mixed reality in medicine The Microsoft HoloLens is a mixed reality head mounted display, which allows users to interact with their environment using a Hologram. Mixed reality (MR) like augmented reality (AR) and virtual reality (VR) are defined like extended reality. Extended reality describes the spectrum of virt...
