The heart is suspended by the great vessels, especially by the aorta and its main branches and the surrounding pulmonary tissue, In this circumstance, the suspending points would be influenced continuously under cyclic cardiac motion, so that pathologic changes were induced in these points, such as the sinus of Valsalva and the orifices of the coronary arteries. In this report, the pathological changes seen in these portions of the aorta were studied in cases with ischemic ECG findings with control group without any ischemic changes.
Results obtained were as follows;
1. The diameter of the aorta at its origin and volume of the aortic valves were well related to the aging.
2. There was no difference between the cases with and without Ischemic changes of ECG with reference to stenotic grade of the coronary atreries.
3. There were some differences in the position of the orifice between the cases with and without ischemic ECG changes. However, its meaning was not clarified at the present time, so intensive study must be done in future.
