Which of the following dissection method of hea is very useful for demonstrating the distribution of infarction?

Sho axis or ventricular slicing method: * Hea in the anatomical position, the first slice is made through the hea at a point about 3 cm from the apex separating it from the remainder of the hea. * Complete slices are then made in parallel to this slice, 1 cm apa, until reaching below the atrioventricular valves. * The remainder is then examined by opening along the path of blood flow. It is useful if ischemic myocardial disease is suspected as it clearly demonstrates the distribution of infarction.
