Abstract

1.
1. Fifty canine hearts, and several human, bovine, feline, and simian specimens have been injected by the above technique to demonstrate coronary and intercoronary anastomotic vessels at post mortem. The method also has yielded superior demonstrations of the septal coronary artery.
2.
2. The technique is rapid, complete, simple, and economical, and a tridimensional cast is visualized.
3.
3. The injection mass is a commercially available product, rapidly injectable and hardens almost simultaneously.
4.
4. Vessels down to the size of 0.03 mm. are easily visualizable, and the distribution of the multicolored masses in the coronary artery branches gives an absolute index of the distribution of the blood from either coronary artery orifice.
5.
5. This injection dye technique is being utilized in an attempt to demonstrate in an objective manner the nature and extent of new sources of blood to the myocardium following revascularization procedures. The matter of these observations will be presented in a future publication.
