MULTIPLE-MYELOMA COMPLICATED WITH STREPTOCOCCAL ENDOCARDITIS SUCCESSFULLY TREATED BY MITRAL-VALVE REPLACEMENT

A 63-year-old male patient with multiple myeloma developed congestive heart failure due to streptococcus endocarditis prior to the initiatio n of chemotherapy. Doppler echocardiographical examination revealed th e presence of a large vegetation on the anterior mitral leaflet as wel l as the association of severe mitral regurgitation. Surgical repair ( mitral valve replacement) was urgently undertaken and the postoperativ e course resulted in uneventful recovery. In immunodeficient patients with such a streptococcus sepsis, the possibility of infectious endoca rditis should be taken into consideration and proper management is man datory in these circumstances.
