This new method of myocardial protection was used to prevent complications of cardiac ischaemia during clamping of the aorta. 4 litres of Ringer lactate at 4 degrees C are used to perfuse the coronary arteries and produce a total, uniform and deep fall of all the pericardial and myocardial system. This results in a flat electrocardiogram, i.e. the interruption of electrical activity of the cardiac cells. This effect persists until the aortic clamp is released which results in reoxygenation, a rise in temperature and the restoration of function. The method has been used in more than 250 operations with extracorporeal circulation (valves, bypass procedures, transplants). Up until the present, it has proved superior to techniques of coronary perfusion or hypothermia obtained using Shumway's technique.
这种新的心肌保护方法用于预防主动脉钳夹期间心脏缺血的并发症。使用4升4摄氏度的乳酸林格液灌注冠状动脉，使整个心包和心肌系统全面、均匀且深度降温。这会导致心电图呈平线，即心脏细胞电活动中断。这种效应会持续到松开主动脉钳，此时会发生再氧合、体温升高以及功能恢复。该方法已在250多次体外循环手术（瓣膜手术、搭桥手术、移植手术）中使用。到目前为止，它已被证明优于使用舒姆韦技术获得的冠状动脉灌注或低温技术。
