Figure 1.

Illustration of the experimental dispositive (Langendorff) used to perfuse and conserve the heart during ischemia reperfusion. Note that the heart is maintained in the water-jacketed chamber during perfusion as well as reperfusion and the ischemic conservation period, and the temperature of perfusion is maintained constant at 36.5°C by a heater circulating pump. A. The heart is kept immersed in a physiological solution bublled either with oxygen or with nitrogen; B. The heart is kept suspended in air the normothermic chamber.
