Which failure mode becomes likely when a patient's aortic valve stenosis increases, leading to reduced cardiac output and increased left ventricular pressure?

A)Increased systemic vascular resistance
B)Decreased baroreceptor firing rate
C)Reduced pulmonary artery pressure
D)Left ventricular hypertrophy develops

💡 Explanation

Left ventricular hypertrophy is likely because the heart muscle must work harder to pump blood through the stenotic valve, thus cardiac muscle thickens over time as a compensatory mechanism. Therefore, hypertrophy is the likely outcome, rather than increased systemic vascular resistance, which is not a direct result of valve stenosis.
