[2025-09-29T13:30:23.848101] [PI reasoning] **Determining endocarditis lesion site**

I’m addressing a question about the lesion site in endocarditis related to rheumatic heart disease (RHD). RHD refers to rheumatic endocarditis, where the typical lesions are verrucae along the valve cusps' closure lines, mainly on the left-sided valves like the mitral valve. Option A fits since it describes this location. I’ll gather some citations for further accuracy, possibly referencing resources like Kumar and PubMed.
