Question

When M-mode evaluation of a systolic ejection murmur reveals thickened aortic valve leaflets and an aortic cusp excursion of 2.0 cm, the most likely diagnosis is aortic valve:

A. Insufficiency
B. Sclerosis
C. Stenosis
D. Vegetation

Answer 1

The most likely diagnosis for a patient with thickened aortic valve leaflets and an aortic cusp excursion of 2.0 cm is aortic valve stenosis.

Step-by-step explanation:

Based on the symptoms described, the most likely diagnosis for a patient with thickened aortic valve leaflets and an aortic cusp excursion of 2.0 cm is aortic valve stenosis. Stenosis is a condition in which the heart valves become rigid and may calcify over time, leading to a narrowing of the valve opening. In the case of aortic valve stenosis, the thickened leaflets impede the flow of blood from the left ventricle to the aorta, resulting in symptoms such as a systolic ejection murmur.
