Atherosclerosis Cross Sections

Cross-sections of multiple arteries from a patient with atherosclerosis, seen as white fatty plaque occluding the arterial lumen. Various degrees of stenosis are seen. Some of vessels showed evidence of plaque rupture and formation of a fully occluding thrombus (black arrows). (courtesy of Dr. Jagdish Butany)

Hypertrophic Cardiomyopathy

The ventricular wall is much thicker compared to that of a normal heart. (courtesy of Dr. Jagdish Butany)
Hypotrophic Cardiomyopathy

Dilated Cardiomyopathy

The ventricle is enlarged with normal thickness of the ventricular wall. Note that this gross specimen also shows a lateral wall infarct stained as white myocardial tissue.
