Abstract:
The normal arterial patterns in the left ventricle wall of 100 rabbit hearts were studied by means of postmortem coronary angiography, the clearing method and histological sections, and in comparison with that of the human heart.The intramural arterial patterns in the left ventricle of rabbit heart are similar to human heart in many ways. "Branching" type arteries (Class A vessels) supply the whole myocardium, including the subendocardial zone, while "straight" type arteries(Class B vessels)mainly supply the papillary muscle and trabeculae carneae where they form the subendocardial plexus. The arterial type in papillary muscles may be classified into segmental pattern, axial pattern and mixed pattern. The arterial distribution in the interventricular septum is without rule. The capillaries in all areas run parallel with the myocardial fibres and show cross connexions somewhere.
