Abstract
The transit time of contrast material through a proximal segment of right coronary and anterior descending arteries were measured from cineangiograms by means of a projector-linked frame counter. The time required for the contrast material to traverse a 15-cm segment from the ostia was more than 800 msec in 58 out of 80 vessels with more than 85% stenosis and only in 12 of 129 vessels with up to 85% stenosis. This simple measurement during routine interpretation of cineangiograms may add valuable information.
