Effects of Aortic Insufficiency on Circulatory Dynamics of the Dog: With Special Reference to Coronary Blood Flow and Cardiac Oxygen Consumption

In dogs with chronic aortic insufficiency accompanied by cardiac hypertrophy, the coronary blood flow, cardiac oxygen consumption, coronary arteriovenous oxygen difference, coronary oxygen utilization, systolic pressure and cardiac rate are increased significantly above the normals, while coronary venous oxygen saturation, coronary resistance and diastolic pressure are significantly decreased.
