Direct revascularization of acute myocardial infarction by implantation of left internal mammary artery into infarcted left ventricular myocardium.
This is a preliminary report. Clearly, the internal mammary artery implanted into the infarcted anterolateral portion of the wall of the left ventricle has been of help in decreasing the size of the infarction and in maintaining the life of the dogs and normal function six hours after a large left ventricular wall myocardial infarction had been created. More animals need to be studied at the end of six hours, eight hours, and ten hours after implantation. More studies are needed to learn if ligation of the coronary veins at the same time as the arteries is beneficial or not. Two internal mammary arteries may act better than one when implanted side by side into a 5 by 5 centimeter infarction. In man, both internal mammary arteries and the right gastroepiploic artery could be used to revascularize acute myocardial infarctions in the posterior and anterolateral parts of the left ventricle.
