Short description: Abnormal growths in the heart associated with endocarditis
In medicine, a vegetation is an abnormal growth[1] named for its similarity to natural vegetation. Vegetations are often associated with endocarditis.[2][3][4] They can be made of fibrin[5] and platelets.[6]
Types
Certain conditions are associated with specific vegetation patterns:
| Condition | Size | Infective? |
|---|---|---|
| Infective endocarditis related to Staphylococcus aureus | Generally large | Yes |
| Rheumatic fever related to Streptococcus pyogenes | Typically small | |
| Libman–Sacks endocarditis related to systemic lupus erythematosus | Small | No (sterile) |
| Nonbacterial thrombotic endocarditis (NBTE) | Small | No (sterile) |
