Stents Installed
This patient had two stents installed in this LAD, which you can see as cylindrical shapes within the vessel.
Stenotic Lesion
LAD with 95% stenotic lesion distal to diagonal branches. (Courtesy of Toronto General Hospital Catheterization Laboratory)
Stenosis LAD
Stenosis of LAD, as well as the circumflex.
Echocardiography
TEE Probe
Probe used in transesophageal echocardiogram. (Courtesy of Dr. Chi-Ming Chow)
Echocardiogram Video
TTE: Transthoracic echocardiogram with Doppler ultrasound showing the four chambers and blood flow. (Courtesy of Dr. Chi-Ming Chow)
Atherosclerosis Histology
Histological view of an atherosclerotic fatty plaque. (courtesy of Dr. Jagdish Butany)
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)
Aortic Dissection
Gross anatomical view of an aortic dissection. The true and false lumens of the dissected aorta are shown (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)
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.
Normal aortic valves

Mechanical Valve In Situ
In this specimen, the aortic valves were replaced with the metallic (Bjork-Shiley) valve. (courtesy of Dr. Jagdish Butany)
Perfusion Scan
Perfusion scan showing blood flow during rest and persantine stress. White areas mark those of ischemia. Irreversible defects are seen with ischemia both at rest and stress. (courtesy of Dr. Chi-Ming Chow)
Cardiac Nuclear Scan
