Which condition is not a cause of increased left ventricle mass?

Increased left ventricle mass typically results from conditions that impose a greater workload on the heart, leading to hypertrophy of the left ventricle. Aortic stenosis, systemic hypertension, and aortic insufficiency are all conditions that create increased afterload or preload, thus stimulating the heart muscle to thicken in response to the greater pressures it must generate.

Aortic stenosis leads to a reduction in the outflow of blood from the left ventricle, causing the heart to work harder to push blood through the narrowed valve, resulting in left ventricular hypertrophy. Similarly, systemic hypertension increases the pressure the left ventricle must overcome to eject blood, which also leads to hypertrophy.

Aortic insufficiency, characterized by the backflow of blood from the aorta into the left ventricle during diastole, increases the volume load on the ventricle and can also cause left ventricular enlargement and increased mass.

On the other hand, mitral valve prolapse primarily affects the mitral valve's function rather than causing a significant increase in the pressure or volume load on the left ventricle in most cases. While it can lead to some degree of left ventricular dilation or volume overload in certain scenarios or with severe cases,
