This animation illustrates how the aortic valve opens and closes to regulate blood flow from the left ventricle into the aorta. It highlights the effects of rheumatic damage—thickening or fusion of valve leaflets—leading to aortic stenosis. Watch the narrowing valve openings, turbulent blood flow, and increased cardiac workload. A clear, visual representation ideal for cardiology trainees, medical students, and healthcare professionals aiming to understand valve dysfunction.
