“Smartphone Assessment Prior Radial Artery Harvesting for CABG”
Coronary artery bypass graft (CABG) surgery is a procedure where surgeons use blood vessels from elsewhere in the body to go around blockages or narrowings in the heart arteries. Before the surgery, the surgeon needs to choose which vessel will be used for the bypass, including potentially the radial artery in the wrist. Smartphones have been shown in a previous study to be a better way to assess the arteries in the hand than the traditional physical examination, as it is less subjective than simply watching the flushing of the hand. In this study, the investigators will assess the utility of a smartphone application in determining whether there is enough blood flow in the hand prior to using the radial artery for CABG surgery.
