Libman-Sacks endocarditis is a condition that affects the heart valves. It is characterized by inflammation and the growth of small, warty lesions on the surface of the valve. This condition is commonly associated with autoimmune diseases such as lupus. Some synonyms for Libman-Sacks endocarditis include rheumatic heart disease, infective endocarditis, valve regurgitation, and valve stenosis. Each of these terms refers to a different aspect of valve dysfunction or damage, but they share many of the same symptoms and risk factors as Libman-Sacks endocarditis. While the condition is serious, treatment options such as antibiotics and surgery can help manage symptoms and improve patient outcomes.
