The commonest valvular lesion in SLE-related cardiac disease is-
Tricuspid regurgitation
Mitral regurgitation
Mitral stenosis
Aoic regurgitation
Valvular involvement is the most encountered form of hea disease in systemic lupus erythematosus (SLE). Immunoglobulin and complement deposition in the valvular structure will subsequently lead to Libman-Sacks vegetations, valve thickening, and valve regurgitation. Valvular stenosis is rarely seen.resulting in mitral regurgitation Ref Davidson 23rd edition pg 455
