Presumably, in the first half of the 1940s, Canadian surgeon Arthur Vineberg pioneered the first implantation of the left internal thoracic artery in dog myocardium, to demonstrate the formation of anastomotic channels between coronary vessels and extracardiac sources of blood supply. Dog 8A, killed 99 days after operation, clearly showed these anastomoses for the first time. Vineberg, trying to demonstrate his finding in more detail, sought the help of a photographic studio in Chicago which (from a black and white photograph published a year earlier) created a color version of the dog's heart, which masterfully shows the distribution, in the entire left coronary artery tree, of a Schlesinger solution injected through the implanted mammary artery.
