ABSTRACT

Presentamos el caso de un hombre de 68 años que ingresó por mareos y sensación de pérdida de la conciencia. El examen clínico reveló una temperatura de 37.5 °C y un soplo de regurgitación mitral. El ecocardiograma mostró una insuficiencia mitral grave con dilatación de las cavidades izquierdas, y el ecocardiograma transesofágico una vegetación en la valva anterior de la mitral. Los hemocultivos demostraron una bacteria Gram-negativa que luego se identificó como Bartonella spp. La PCR demostró que se trataba de una Bartonella quintana. Se trató con gentamicina, doxiciclina y ceftriaxona, evolucionando satisfactoriamente. La insuficiencia mitral remanente espera el tratamiento quirúrgico.


We present the clinical case of a man of 68 years who was admitted for dizziness and sensation of loss of conscience. The clinical examination revealed a body temperature of 37.5 °C and a murmur of mitral regurgitation. The echocardiogram showed a severe mitral regurgitation and left cavitie's dilatation; transesophageal echocardiogram showed a vegetation in the anterior leaflet of the mitral valve. In blood cultures grew a Gram-negative bacteria identified as Bartonella spp. A PCR demonstrated that it was a Bartonella quintana. The patient was treated with gentamicin, doxiciclin and ceftriaxone with satisfactory evolution. The remaining mitral insufficiency awaits surgical treatment.
