Patient Data

Age: 60 years
Gender: Female

Large mobile echogenic irregular mass attached to the atrial side of the anterior mitral leaflet

Significant mitral regurgitation (Coanda effect)

Aortic regurgitation 

Hyper-dynamic left ventricule

Case Discussion

This patient presented with acute limb ischemia, however, during her cardiac evaluation, her echo study showed a large mass on the anterior mitral valve leaflet.

Her echo findings showed vegetation on the atrial side of the anterior mitral leaflet. Blood culture was positive for Staphylococcus aureus. Eventually, the patient was transferred to cardiovascular surgery due to the clinical\echocardiographic deterioration despite antimicrobial therapy.

This embolic event possibly related to the migration of vegetations, which more often to be seen with large vegetations (>10 mm).

The general approach of infective endocarditis treatment is initial clinical stabilization, early blood cultures, and medical and/or surgical treatment.

Antibiotic treatment depends on whether the involved valve is native or prosthetic, as well as on the causative microorganism and its antibiotic susceptibilities.
