II/2.2: Description of the specimen
|
 |
A heart weighing 510 g with a smooth, shiny and reflective visceral pericardium on its surface, and moderate amount of fat tissue under the serous membrane coating. The heart chambers are significantly dilated, especially the left ventricle, which has a rounded apex, 1.5 cm wall thickness, while the right ventricular wall thickness is 0.4 cm . The cardiac valves – except for the aortic valves – are membranous, intact and moveable in every position, and the tendinous cords belonging to the atrioventricular valves are thread-thick.
The cusps of the aortic valve are vastly thickened on their free edges; nodules containing connective tissue and calcification are seen with cusp fusion . The outflow tract is narrowed to 60% due to cusp stiffness, and the valve didn’t obstruct the reflow during the aortic root’s water fillling test. Coronary artery pathways are straight and regular, and their lumens are slightly narrowed by calcified appositions at places . The myocardium has intact fine fibrous structure on the cut surfaces, and no focal alterations are seen within.
