Abstract We describe a technique useful in complex coronary interventions wherein timed bilateral contrast injections are given in both coronary arteries. This technique is useful in chronic total occlusions in which the distal coronary vessel is not visualized except by collateral filling via the contralateral artery. This technique was applied in 12 patients; 11 with native coronary occlusion and one in whom the target site was visualized by contrast injections into a vein graft supplying competitive flow to an otherwise patent native vessel. With this technique, the distal coronary artery segment can be better visualized, which helps to aim and track the guide wire across the occluded segment.
