Rheumatic fever associated with MAC causes fibrosis of the:

Explanation:
Rheumatic fever primarily causes inflammatory scarring of the mitral valve leaflets. The immune-mediated process thickens and fuses the leaflet tissue and commissures, leading to restricted leaflet motion and often mitral stenosis. While other structures around the valve (the annulus, chordae tendineae, or papillary muscles) can be involved secondarily, the most characteristic fibrotic change in rheumatic disease is in the valve leaflets themselves.
