I have a collection of scans from my teaching file that I used in the classroom at Rhode Island Hospital. I performed and processed the majority of these scans myself. Be advised that these images are offered as examples of typical and atypical findings, solely for the viewer's benefit. Patient histories and reports are not available, and identifying information has been removed from the photographs.

The Left Anterior Descending Coronary Artery delivers blood to about fifty percent of the myocardium. The LAD has been nicknamed “the widowmaker”. Slideshow displays 10 seconds per frame.
The LCX artery feeds the lateral wall of the left ventricle. Slideshow displays 10 seconds per frame.
The RCA perfuses the posterior wall of the left ventricle.
Congestive heart failure describes a condition that impairs the normal pumping of the heart, caused by myocardial infarction, atherosclerosis, or cardiomyopathy. In CHF, blood is not efficiently ejected from the left ventricle, resulting in volume overload, chamber dilation, and abnormal intracardiac pressure, followed by pulmonary and venous congestion and peripheral edema. Left Ventricular Ejection Fraction will be below 35% and we often see global decrease in elasticity, thin left ventricle muscle, and patchy or mottled tracer uptake.
