Summary
An abdominodiaphragmal way of producing right-ventricular myocardial infarction is introduced, allowing ligation of the right-coronary artery and vein without further manipulation of the heart.
Of the rats operated upon, 22% died perioperatively. Of the surviving part, 89% had myocardial infarction macroscopically.
This method was used to study enzyme decreases in infarcted myocardium. Our biochemical results correlate very well with histological and histobiochemical findings reported by other investigators. Therefore, we conclude that right-coronary artery ligation in rats by transabdominal, transdiaphragmal access to the heart can be a useful way to study biochemical aspects of infarcted myocardium.
