Aortic stenosis associated with systemic lupus erythematosus.

Area of Science:

• Cardiology
• Rheumatology
• Pathology

Background:

• Libman-Sacks endocarditis is a rare cardiac complication of systemic lupus erythematosus (SLE).
• Hemodynamically significant valvular lesions are infrequently reported in SLE patients.
• Embolic phenomena from Libman-Sacks vegetations are not well-documented.

Observation:

• A patient with a history of long-term corticosteroid treatment for SLE developed critical aortic stenosis.
• Necropsy revealed an embolus in the left anterior descending artery, histologically identical to the aortic valve vegetation.
• Other causes of valvular disease, including rheumatic heart disease, bacterial endocarditis, and bicuspid aortic valve, were excluded.

Findings:

• This case demonstrates a direct link between Libman-Sacks endocarditis in SLE and severe aortic stenosis.
• The findings confirm embolic potential from Libman-Sacks vegetations.
• The patient's history of long-term corticosteroid use may be a contributing factor.

Implications:

• Libman-Sacks endocarditis can lead to severe valvular dysfunction and embolic complications in SLE patients.
• Long-term corticosteroid therapy in SLE may increase the risk of valvular heart disease.
• Further research is warranted to understand the association between SLE, corticosteroid treatment, and valvular pathology.
