Endocarditis Types
Summary slide (p. 318) of types of endocarditis
| Type of Endocardits | vegetation size/description | Infected Valve/location | Other Features |
|---|---|---|---|
| Infective Endocarditis | • Large (up to 3 cm) • Friable • Tan/red/grey/brown | • most commonly of valves: 35% mitral alone, 20% aortic alone and 20% both • Vegetations on atrial side of AV valves and ventricular side of semilunar valves | • Uncommon • 70% have predisposing heart disease • 100% fatal if undiagnosed and untreated |
| Acute Rheumatic Endocarditis | • Tiny (1-2 mm) | • Usually on the line of valve closure | • Microscopic Aschoff bodies • Later fish-mouth or buttonhole mitral stenosis • Later thickened, fibrotic, fused chordate tendineae |
| Marantic Endocarditis | • Small (1-5 mm) • Red-tan | • Most common on atrial side of mitral valve line of closure • Second most common on ventricular side of aortic valve | • Common • Commonly embolize • Sometimes converted to infective endocarditis |
| Libman Sacks Endocarditis | • Small-medium • Red • Variable shape | • Commonly multiple valves • On either or both sides of the valves | • Part of SLE • usually with simultaneous pericarditis • NO EMBOLI from vegetations |
