Valves commonly affectedMitral aloneMitral and aortic combinedMitral, tricuspidMainly bacterial less often aortic and tricuspidMitral, aortic combined mitral and aortic2. Location on valve cusps or leaflets* Occurs along the line of closure, atrial surface of AV valves and ventricularOccurs in both surface of valve leaflets or cusps in the valve pocketsOccurs along the line of closureSABE more often on diseased valve ABE on previously normal surface of semilunar valves valves, location same as in RHD3.
