The surgical technique of cardiopulmonary bypass with either an empty beating or an empty fibrillating ventricle produces marked changes in the regional blood flow and oxygen demand of the left ventricle. This paper describes the changes which occurred in the regional perfusion of both the normal and the hypertrophied left ventricle during these conditions and relates them to the known changes in oxygen demand. It also correlates the changes in flow with the measurable changes in myocardial tissue pressure-systolic when the heart is beating and continuous when fibrillating. The various types of filbrillation had identical effects on both regional tissue pressure and regional flow. The subendocardial blood supply was adequate or more than adequate under each of these conditions so long as the coronary perfusion pressure was maintained at an adequate level. A low perfusion pressure during ventricular fibrillation of any type led to a marked reduction in flow to the subendocardial portion of the left ventricle: The presence of ventricular hypertrophy accentuated this danger.
