Arterial Stenosis - Video Lesson

Hey, everybody. Welcome back to today's lesson on hemodynamics. This lesson covers arterial stenosis, which is a narrowing of an artery. We will focus on identifying common locations, discussing its effects on blood flow, and explaining the application of Bernoulli's principle to calculate pressure gradients and assess clinical significance. Let's get started. Arterial stenosis is the narrowing of an artery, reducing its cross sectional area and impairing normal blood flow. It may occur due to plaque buildup, also called atherosclerosis, inflammation, or external compression. Although any artery can develop a stenosis, some common areas for arterial stenosis within the body are the carotid arteries, coronary arteries, peripheral arteries like the femoral or popliteal arteries in the legs, and renal arteries. Identifying stenotic locations is essential for preventing, diagnosing, and managing conditions like stroke, cardiac ischemia, and
