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 initiation of chemotherapy. Doppler echocardiographical examination revealed the presence of a large vegetation on the anterior mitral leaflet as well as the association of severe mitral regurgitation. Surgical repair (mitral valve replacement) was urgently undertaken and the postoperative course resulted in uneventful recovery. In immunodeficient patients with such a streptococcus sepsis, the possibility of infectious endocarditis should be taken into consideration and proper management is mandatory in these circumstances.
