{{{header}}} edit

  • Remove the parietal pericardium
  • Separate the heart from the from lungs by cutting through the major vessels. The pulmonary artery should be cut first and the lumen inspected for any pulmonary embolism.
  • Weigh the heart.
  • Dissect the coronary vessels. {{{coronary note}}} Further information: Arteries
  • On the right side of the heart, dissect in the direction of blood flow: Superior vena cava > right atrium > tricuspid valve > right ventricle. Look for thromboses or patent foramen ovale.[notes 1]
  • Dissect the atrial appendages, to exclude thromboses.
  • Dissect the left ventricle, such as into circumferential slices from the apex to the base.[notes 2] Inspect (and measure) the left ventricular wall thickness.
Valve circumferences are measured at the basal ring (bottom in image).
  • (Measure the circumferences of the four valves.)

Notes

  1. The right ventricle can alternatively be cut in circumferential slices along with the left ventricle.
  2. An alternative approach is to cut the left ventricle through a cut along the left lateral margin, followed by an anterior cut from the apex to the aortic root, freeing the anterior wall. Then cut through the plane of the myocardium of the anterior and posterior myocardial wall, as well as the septum, for any signs of infarction. (Dissect one or more papillary muscles for infarction.)
