CT Coronary Artery Disease - Video Lesson

Hey everybody, welcome back. This lesson is about coronary artery disease. Evaluation of coronary artery disease used to be the exclusive domain of interventional radiology, but CT imaging has become more useful in recent years. Coronary artery disease or CAD, sometimes called CAD, is narrowing of the coronary arteries, primarily due to atherosclerotic plaques. This condition can lead to myocardial ischemia and myocardial infarction. An atherosclerotic plaque is an accumulation of cholesterol and other materials that forms inside of an artery. These plaques deform the arterial lumen leading to stenosis. Within the heart. This arterial stenosis is very significant because it can lead to myocardial ischemia, a term that refers to decreased blood flow into the heart muscle. If this condition is left unresolved, it leads to myocardial infarction, referring to the irreversible death of heart muscle. Myocardial infarction is the medical
