An effect of significant aortic valve stenosis on the left ventricle is:

A. Asymmetrical septal hypertrophy
B. Concentric left ventricular hypertrophy
C. Eccentric left ventricular hypertrophy
D. Protected in significant aortic valve stenosis

Answer :

Final answer:

Significant aortic valve stenosis leads to Concentric left ventricular hypertrophy due to the increased workload on the left ventricle to pump blood through the narrowed valve, resulting in thickened ventricular walls.

Explanation:

An effect of significant aortic valve stenosis on the left ventricle is Concentric left ventricular hypertrophy. Aortic stenosis causes the left ventricle to work harder to pump blood through the narrowed valve. Over time, this increased workload leads to the thickening of the ventricular walls to maintain adequate blood flow into the systemic circulation, which is termed concentric hypertrophy. This is characterized by a uniform increase in wall thickness without an increase in the size of the ventricular cavity.
