RESUMO

Resumen La endocarditis infecciosa es un proceso patológico de baja incidencia en la clínica diaria; su principal etiología son los agentes bacterianos, los cuales colonizan con mayor prevalencia de válvula mitral y aortica. En este artículo se presenta el estudio de un perro con diagnóstico previo de síndrome vestibular periférico secundario a probable otitis media-interna. Se presenta con un soplo de aparición súbita, claudicaciones intermitentes, inapetencia, depresión y fiebre, por lo cual se hace la valoración ecocardiográfica, donde se evidencia engrosamiento valvular mitral, acompañado de estructuras hiperecoicas en el borde libre que corresponden a lesiones vegetativas. Por medio de los criterios de Duke modificados se obtiene un diagnóstico definitivo de endocarditis infecciosa, para lo cual se realiza manejo médico intrahospitalario, sin evolución favorable. Los hallazgos clínicos y paraclínicos coinciden con lo reportado en la literatura. Los criterios de Duke modificados permiten orientar el diagnóstico y evidenciar signos clínicos de alarma. El manejo médico antimicrobiano deberá realizarse con base en hemocultivos y pruebas de sensibilidad, siempre teniendo en cuenta la prevalencia de patógenos y el origen primario de la infección. Se debe considerar como una patología con un pronóstico malo y un porcentaje de fatalidad alto. Finalmente, se concluye que la principal limitación del caso es la falta de confirmación histopatológica.


Abstract Infectious endocarditis is a pathological process with low incidence in the daily clinical practice. The main etiology are the bacterial agents that colonize with higher prevalence the mitral and aortic valves. This paper reports the case of a dog with a previous diagnosis of peripheral vestibular syndrome secondary to probable otitis media-interna. The dog has a sudden heart murmur, intermittent claudications, lack of appetite, depression and temperatures. It is performed an echocardiographic assessment that shows mitral valve thickening with hyperecoic structures in the free border that indicates vegetations. Using the Modified Duke Criteria, a definitive diagnosis of infectious endocarditis is concluded. The dog is provided a medical treatment at the clinic without success. The clinical and paraclinical findings match the background found in the literature. Modified Duke Criteria allow guiding the diagnosis process and uncovering the alarm clinical signs. Antimicrobial clinical treatment must be administered based on blood cultures and sensitivity tests and considering both the pathogen prevalence and infection primary origin. Doctors must deem this condition as a bad prognosis pathology with a high mortality percentage. Finally, it is concluded that the main limitation in this case is a lack of histopathological confirmation.

RESUMO

Prosthetic valve endocarditis is a major diagnostic challenge in clinical practice, due to the lower sensitivity of the modified Duke criteria and a higher percentage of cases with negative or inconclusive echocardiography results. The delay in establishing medical and surgical treatment increases the morbidity/mortality rate. New imaging techniques and 18F-FDG PET/CT in particular have meant a significant advance in cases of high clinical suspicion and negative or inconclusive echocardiography, increasing the overall sensitivity of the modified Duke criteria. We report the case of a male patient with prosthetic valve endocarditis, where 18F-FDG PET/CT provided the diagnostic key, determining the origin of the endocarditis and avoiding treatment delay.
