Gross cardiac evaluation of infarct size and distribution. Gross cardiac evaluation at 8 weeks post-MI showed a multifocal, pale, light tan, firm area in the left ventricular posterior wall, midway between the apex and left circumflex coronary artery (arrows) (a). Transverse sections of the heart showed that the infarcted area extended into the full thickness of the myocardium with subsequent ventricular wall thinning when compared to the adjacent normal myocardium (b).
