The pericardial sac is adhered to the entire surface of the heart. The 402 gram heart has a tan, smooth epicardium, with the usual amount of subepicardial fat. The external configuration of the heart is moderate dilated and mildly hypertrophied. The right ventricle ranges from 0.25 cm to 0.55 cm in thickness. The free wall of the left ventricle is 1.0 cm in thickness. The interventricular septum is 1.7 cm in thickness. The diameters of the right and left ventricles are 4.0 cm and 3.7 cm respectively. The circumferences of the aortic, mitral, pulmonary and tricuspid valves are 6.3, 11, 8, and 11 cm respectively. The endocardium overlying the right and left ventricles is thickened. The mitral valve leaflets are thickened and are slightly nodular. The aortic valve cusps are mildly sclerotic. The remaining heart valve leaflets and cusps are smooth and transparent and are free of
abnormalities. No vegetations or deformities are noted. The trabeculae carneae and papillary muscles are mildly hypertrophied. The chordate tendineae are unremarkable.
The right and left coronary ostia are patent. The right coronary ostium is partially narrowed by an atherosclerotic plaque. The right and left coronary arteries are of medium caliber, with a right-dominant coronary artery and are mildly to moderately involved with atherosclerotic plaques. The myocardium is red-brown with discrete streaks of white fibrosis. The anterior wall of the left ventricle is slightly thinned. The remaining myocardium is homogeneous with the usual consistency.
The aworta has multi focal moderate to severe atherosclerotic plaques. The ostia of the celiawc trunk, superior mesenteric artery and inferior mesenteric artery are patent. The ostium of the left renal ostium is 80% occluded by red atheroma.
The venae cavac are unremarkable.
