Endocarditis infecciosa por granulicatella adiacens: reporte de un caso / Infective endocarditis due to granulicatella adiacens: a case report

ResumenEl diagnóstico de endocarditis infecciosa subaguda causa un reto para el clínico, puesto que puede simular otra entidad que confunde el diagnóstico. La endocarditis por Granulicatella adiacens es poco frecuente, sin embargo es un microorga nismo difícil de aislar y cultivar ya que requiere un medio especial para crecer. El porcentaje de endocarditis con cultivos negativos es alto y este podría estar enmascarando microorganismos no identificados. Se presenta un caso muy intere sante de endocarditis por el germen mencionado, donde el tiempo de diagnóstico y de identificación del microorganismo pudieron ser cruciales en el manejo y desenlace del paciente.

AbstractSubacute infective endocarditis is a challeging diagnosis for the clinician, since it can simulate other entities that confound the final diagnosis. Endocarditis by Granulicatella adiacens is rare, and it is a difficult organism to isolate, because it needs a special culture medium to grow. The percentage of culture - negative endocarditis is high and this could be masking unidentified microorganisms. In the following case report, we present an interesting case of endocarditis, whose diagnosis and the time for microorganism identification may have been crucial in the management and patient outcome.

Aortic Saddle Embolism Caused by Mitral Valve Vegetation

Aortic saddle embolus accounts for approximately 10% of all peripheral arterial emboli. The most common sources of emboli are left atrial thrombi associated with atrial fibrillation and vegetation. A 22-year-old male patient was admitted due to acute onset of orthopnea, tachypea and cough. Transthoracic and transeophageal echocardiography showed huge vegetation (3X2cm) of the posterior mitral valve leaflet which was associated with severe mitral regurgitation. On 14th hospital day, he suffered from sudden onset of weakness, pain, and coldness on both lower extremities. Follow-up echocardiography showed marked size reduction of the original mitral valve vegetation. Angiography showed aortic saddle embolus. The embolectomy of aortic saddle embolus was performed through the transfemoral approach with a Forgarty catheter. At the same time, removal of the infected mitral valve and mitral valve replacement were performed.
