ABSTRACT

La endocarditis infecciosa es una patología heterogénea con una alta mortalidad y requiere tratamiento quirúrgico en al menos la mitad de los casos. Cuando asienta en posición mitral, la reparación valvular en lugar de su sustitución, si bien representa un desafío técnico, ha ido ganando terreno en los últimos años. Describimos el caso de un paciente que se presentó con una endocarditis sobre válvula nativa mitral en quien se realizó una plastia valvular exitosa. Revisaremos la evidencia acerca de su beneficio.


Infective endocarditis is a heterogeneous disease with a high mortality and that requires surgical treatment in at least half of cases. When seated in mitral position, valve repair rather than replacement, while technically challenging, has been gaining popularity in recent years. We describe the case of a patient who presented with a mitral valve endocarditis in whom a successful valve repair was performed. Evidence supporting its use will be reviewed.

Quando sentado na posição mitral, o reparo da válvula, em vez da substituição da válvula, embora seja um desafio técnico, tem ganhado espaço nos últimos anos. Descrevemos o caso de um paciente que apresentou endocardite valvar mitral nativa, no qual foi realizada plastia valvar com sucesso. Vamos revisar as evidências sobre o seu benefício.

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.

ABSTRACT

OBJETIVO: Descrever o caso de uma criança com endocardite infecciosa causada por Haemophilus aphrophilus. DESCRIÇÃO: Menino com febre e calafrios há 20 dias. À internação, apresentava-se febril, descorado e sem sinais de instabilidade hemodinâmica; à ausculta cardíaca, tinha sopro holosistólico em foco mitral. Os exames laboratoriais identificaram anemia (hemoglobina = 9,14 g/dL), leucócitos totais de 11.920 mm³, plaquetas de 250.000 mm³, velocidade de sedimentação das hemácias e proteína C reativa elevadas. O ecocardiograma revelou imagem em válvula mitral, sugestiva de vegetação. Com a hipótese de endocardite, foi iniciada antibioticoterapia com penicilina cristalina (200.000 UI/kg/dia) associada à gentamicina (4 mg/kg/dia). No terceiro dia de tratamento, foi identificado Haemophilus aphrophilus em hemoculturas, sendo então trocado o esquema antibiótico para ceftriaxona (100 mg/kg/dia). No 20º dia de internação, encontrava-se pálido, mas sem febre e sem outras queixas. Os exames mostravam hemoglobina = 7,0 g/dL, leucócitos = 2.190 mm³, plaquetas = 98.000 mm³, razão normatizada internacional = 1,95 e R = 1,89. Foi feita hipótese de reação adversa ao ceftriaxona, que foi substituído por ciprofloxacina, 20 mg/kg/dia, até completar 6 semanas de tratamento. Após 72 horas da troca, houve normalização dos exames. Durante seguimento ambulatorial, apresentou insuficiência mitral grave, sendo submetido a troca de válvula por prótese metálica 9 meses após quadro agudo. Há 3 anos encontra-se bem, em acompanhamento ambulatorial. COMENTÁRIOS: É rara a identificação de agentes do grupo HACEK (Haemophilus ssp, Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens e Kingella kingae) em crianças com endocardite infecciosa. O caso apresentado, sem fatores de risco relacionados a esses agentes, reafirma a necessidade de tentar sempre identificar o agente etiológico das endocardites para adequação do tratamento.


OBJECTIVE: To report the case of a child with infective endocarditis caused by Haemophilus aphrophilus. DESCRIPTION: Boy with 20 days of fever and chills. On admission, he was febrile, pale and with no signs of hemodynamic instability; on cardiac auscultation, a mitral-related holosystolic murmur was observed. Laboratory examination identified anemia (hemoglobin = 9.14 g/dL), total leukocytes of 11,920 mm³, platelets of 250,000 mm³, elevated sedimentation velocity of red cells and elevated C-reactive protein. The echocardiogram revealed image on mitral valve, resembling vegetation. Considering endocarditis, antibiotic therapy was started with crystalline penicillin (200,000 UI/kg/day) in association with gentamicin (4 mg/kg/day). On the third day of treatment, Haemophilus aphrophilus was identified in the blood cultures and the antibiotic scheme was replaced with ceftriaxone (100 mg/kg/day). On the 20th day of evolution, the patient was pale but with no fever or other complaints. Examinations showed hemoglobin = 7.0 g/dL, leukocytes = 2,190 mm³, platelets = 98,000 mm³, international normalized ratio = 1.95 and R = 1.89. Considering the hypothesis of adverse reaction to ceftriaxone, a 6-week replacement treatment with ciprofloxacin (20 mg/kg/day) was started. Examination results normalized after 72 hours of the replacement therapy. During ambulatory follow-up, patient presented with severe mitral regurgitation, undergoing a valve replacement with a metallic prosthetic valve 9 months after acute event. Patient has done well throughout the 3-year ambulatory follow-up. COMMENTS: Identification of agents of the HACEK group (Haemophilus ssp, Actinobacillus actinomycetemcomitans,Cardiobacterium hominis, Eikenella corrodens and Kingella kingae) in children with infective endocarditis is rare. This case report, with no HACEK agent-related risk factors, reinforces the need for identification of the etiological agent of endocarditis to ensure adequate treatment.

ABSTRACT

Endocarditis is increasingly becoming a disease of the elderly. We report a case of a 70 year old man with coronary artery disease, who presented with chest pain and fever. His cardiac markers were elevated and an echocardiogram revealed large vegetation on the anterior leaflet of the mitral valve. He also had severe mitral regurgitation and hypokinesia of the posterior and inferior wall. The association of a mitral regurgitant valve secondary to myocardial infarction and bacterial endocarditis has not been reported in the literature making this case unique and interesting. A discussion on the changing patterns of infective endocarditis reveals interesting facts which are useful in the management of such cases
