  • Abstract
  • Look Inside

To predict the coronary artery bypass graft (CABG)flow based on the time density curve (TDC) obtained from the digital subtraction aortograms (DSA), we developed a pulsatile CABG model (perfusion pressure 60, 130 mmHg, pulse rate 53,126/min, cardiac output 3-7 l/min, diameter of the graft 2.1~6.0mm).

After positioning the regions of interest (ROI), we injected contrast medium (5~40 ml/sec, 5~40 ml) into the outlet conduit.
