Answer
Aortic stenosis is a condition where the aortic valve of the heart narrows. The aortic valve is located between the left ventricle and the aorta, the main artery that carries oxygen-rich blood to the rest of the body.
Step-by-step solution
3 stepsWhen the aortic valve narrows, it restricts blood flow from the left ventricle into the aorta.
This forces the left ventricle to work harder to pump blood through the narrowed valve.
Over time, this increased workload can lead to thickening of the left ventricle muscle (hypertrophy) and can eventually cause symptoms like chest pain, shortness of breath, dizziness, and fatigue.
