Question

Vegetation in mitral valve seen in which condition

• A. Libman sacks
• B. Infective endocarditis
• C. NBTE
• D. Rheumatic fever

Answer 1

The Correct Option is B

Vegetation in the mitral valve is a pathological finding that can be seen in several conditions. It refers to the presence of abnormal growths or lesions on the heart valves, which are often infected or inflamed.

• Libman-Sacks endocarditis: This condition involves sterile vegetations and is associated with systemic lupus erythematosus. The vegetations are typically bland and non-infectious.
• Infective endocarditis: This is the correct answer. In this condition, vegetations involve bacterial or fungal infections, leading to the accumulation of microorganisms on the heart valves, commonly the mitral valve.
• Non-bacterial thrombotic endocarditis (NBTE): This condition involves the formation of sterile vegetations due to hypercoagulable states, often associated with malignancy or chronic diseases.
• Rheumatic fever: Rheumatic fever can lead to rheumatic heart disease, where the mitral valve may be involved, but it primarily involves scarring and stenosis rather than vegetations.

Thus, while vegetations can occur in several conditions, infective endocarditis is characterized by the infectious nature of these vegetations, distinguishing it from other conditions mentioned.
