“…Currently, the majority of the research in the field is carried on in in vitro or computerised models that cannot take into account all possible graft configurations. Tremblay et al (31) performed the only study up to date that uses CCTA to identify morphological and morphometrical factors associated with a saphenous vein bridge (SVB) dysfunction. They analysed SVB length, SVB segment lengths, SVB lumen sectional areas, anastomostic angulations and intrinsic SVB angulations on a group of 40 patients and concluded that CT could be used to identify quantitative graft parameters associated with graft dysfunction.…”

The aim of the current study was to identify surgical factors associated with long-term patency of grafts used in coronary artery bypass grafting (CABG). The present study analyzed data from 127 patients who underwent CABG at our institute between 2000 and 2006 and presented for ambulatory examination and coronary computed tomography angiography evaluation of graft patency in 2016 (139.78±36.64 months post-CABG). The 127 patients received 340 grafts (2.68 grafts/patient) and 399 distal anastomoses (3.14 anastomoses/patient), 220 (55.14%) with arterial grafts and 179 (44.86%) with saphenous vein grafts. Graft patency varied according to coronary territory, proximal anastomosis type (in situ graft, composite graft, graft anastomosed to the ascending aorta), Y anastomosis angle (47.21° for patent arterial grafts vs. 56° for occluded), and distal anastomosis angle (in sequential anastomoses irrespective to graft type, 48.60° for patent side-to-side anastomosis vs. 53.97° for occluded, 65.12° for patent end-to-side anastomosis vs. 90.80° for occluded; in single end-to-side anastomosis of arterial grafts, 39.46° for patent and 44.94° for occluded). A single end-to-side anastomosis angle 60° or greater was associated with a 5.149 occlusion odds ratio (OR) (P<0.001) for arterial grafts. Venous grafts were not sensitive to single end-to-side anastomosis angle. In conclusion, a small anastomosis angle for proximal Y and distal anastomoses is associated with a higher long-term patency of the free graft. Radial artery grafts registered higher patency rates when anastomosed to the ascending aorta compared with composite grafting with the left internal thoracic artery, whereas in situ right internal thoracic artery (RITA) anastomosed to the right coronary territory is associated with a lower patency rate compared with free RITA used to revascularise the anterolateral or circumflex territory in composite grafting.

“…VR technology can bring users a variety of sensations such as strong vision, auditory sensation, tactile sensation and even taste sensation that traditional human-computer interaction [4][5] cannot provide. This is because VR technology firmly grasps the five senses of the human body and constructs a 1:1 three-dimensional model of the real world and the virtual world [6], so that users can have an "immersive" feeling and experience in various aspects when using it; second, it is interactive. VR devices can provide feedback based on user instructions to achieve human-computer interaction; third, they are immersive.…”

VR technology can simulate the complex environment; break through the limitations of traditional physical education curriculum on sports venues, equipment, safety and other aspects. It can provide scientific and accurate guidance for learners and obtain more technical knowledge by visualizing the complex and abstract sports theoretical knowledge. Compared with the traditional sports teaching activities, virtual reality technology can not only simulate the sports scene by generating VR panorama. On this basis, it can effectively improve learners' enthusiasm and motor skills. At present, due to the immaturity of VR technology and the high price of related equipment, people are cautious about the use of VR technology, so VR technology has not been popularized in education. In view of this situation, this paper studies whether VR technology can be effectively applied to physical education teaching and sports training. This paper is divided into four parts: the first part is the research of VR panorama; the second part is the research of VR video; the third part is the application of VR technology in physical education; the fourth part is the investigation. It is found that VR, as a new technology, has great application potential. As long as it is scientifically and reasonably used, VR can greatly promote the improvement of sports scene and the level of sports.
