==An Autopsy Report==
A 68-year-old man initially sought medical advice five years prior to his death. His symptoms at that time were [[exercise intolerance]] and occasional [[peripheral edema]]. He gave a history of a "[[heart murmur]]" that was diagnosed 25 years ago during an employment physical. No follow up care had been given for this murmur.
The patient's terminal admission was for signs of severe [[heart failure]]--the patient had marked [[peripheral edema]] and [[shortness of breath]] and [[chest x-ray]] revealed significant cardiac enlargement and [[pulmonary edema]] with bilateral [[pleural effusion]]s. He sustained a [[cardiac arrest]] shortly after admission and could not be resuscitated.
===Autopsy Findings===
Autopsy disclosed a markedly enlarged heart weighing 650 grams and having dilated chambers. The aortic valve was calcified and showed evidence of stenosis and insufficiency. The coronary arteries were narrowed 60 to 70% by atherosclerosis. No acute coronary occlusions were found and there was no evidence of [[myocardial infarction]].

Overview

Gross anatomy dissection may be used as a diagnostic tool in the evaluation of aortic stenosis. Common findings associated with aortic stenosis include left ventricular hypertrophy and heart block.

Pathological Findings

Pathological findings of congenital or acquired aortic stenosis in adults results in thickening and calcification of aortic valve. Following patterns may be seen:[1]

  • Calcified bicuspid valve involving anterior or posterior cusps
  • Calcified aortic valve cusps with fusion of commissures seen in post rheumatic cases
  • Degenerative calcific aortic stenosis which shows sinuses of valsalva filled with calcium deposits seen in age >70
