Infarcted areas after ligation. Size of the myocardial infarction in slices of rat hearts after LAD ligation for 120 min, aortic clamping with Bretschneider or Buckberg cardioplegia for 90 min, and reperfusion for 90 min. A) Typical appearance of infarcted area (pale tissue, red arrow) compared with non-infarcted area (red tissue, blue arrow) after coronary artery ligation (Buckberg cardioplegia). B) Differential pattern of infarcted areas after Bretschneider cardioplegia with ischemic areas unevenly distributed in the myocardium
