Left Anterior Descending Territory

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.

Left Circumflex

The LCX artery feeds the lateral wall of the left ventricle. Slideshow displays 10 seconds per frame.

 

Heart Failure

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.
