Which part of the heart is primarily affected in aortic stenosis?

Left atrium
Left ventricle
Right ventricle
Right atrium

The correct answer is: Left ventricle

In cases of aortic stenosis, the primary area of the heart that is most significantly impacted is the left ventricle. Aortic stenosis leads to a narrowing of the aortic valve, which impedes blood flow from the left ventricle into the aorta during systole. As a result, the left ventricle has to generate higher pressures to overcome this obstruction. Over time, the increased workload causes the left ventricle to undergo hypertrophy, or thickening of its muscular walls, as it adapts to the added strain of pumping against the narrowed valve. The condition can lead to several complications, including heart failure, due to the left ventricle's inability to handle the elevated pressures efficiently, as well as potential arrhythmias or ischemic events when the heart muscle does not receive adequate blood supply. Therefore, understanding the direct impact of aortic stenosis on the left ventricle is crucial for diagnosing and managing the condition effectively.
