Sclerosis is a precursor for stenosis. True or False?

• A. False
• B. True
• C. Not specified
• D. Not applicable

Answer: (B)

In valvular disease, sclerosis means thickening and calcification of the valve leaflets that makes them stiffer but doesn’t yet cause major narrowing. That stiffening and calcific burden set the stage for reduced leaflet mobility, progressive narrowing of the valve orifice, and increased gradients across the valve. As calcification and fibrosis accumulate, the valve area shrinks and the obstruction becomes clinically significant—that’s stenosis. So sclerosis is commonly viewed as a precursor to stenosis because it represents the early structural changes that can progress to obstructive narrowing. On echocardiography, you might first see thickened, calcified, echo-bright leaflets with a normal or near-normal valve area; over time, progression leads to measurable stenosis with increased gradients. Not every case that shows sclerosis becomes hemodynamically significant stenosis, but the relationship is that sclerosis can precede it.
