The work of Wearn (1933) describing the myocardial circulation, with its myocardial sinusoids and arterio-luminal vessels, was confirmed by Vineberg in 1945. He reported implanting the left internal mammary artery into the wall of the left ventricle. The intercostal branches were open and bled freely into the myocardial tunnel through which the internal mammary artery had been drawn. In no single instance, in either animal or human heart, was there a myocardial hematoma. The implanted arteries not only remained open, but sent out branches which anastomosed with those of the surrounding coronary vessels.
