ABSTRACT

One case of acute bacterial endocarditis of the tricuspid valve caused by S. aureus and following a septic abortion is presented. Surgical treatment was indicated after failure of antibiotics. Operation consisted of excision of a large vegetation adherent to the anterior and posterior cusps at the commisure and of the affected valvar tissue. Annular plicature at the segment corresponding to the posterior cuspid was employed to maintain competence. Clinical result was very satisfactory with resolution of sepsis. Dopplerecocardiography revealed the presence of the vegetation before the operation and showed a small regurgitation after valvoplasty. Conservative operation upon the atrioventricular valves must be kept in mind as an alternative in the treatment of acute bacterial endocarditis.

RESUMO

É relatado o caso de 1 paciente que apresentou endocardite aguda da valva tricúspide pós-aborto, cujo agente causal era o S. aureus. Como não houvesse resposta favorável ao tratamento antibiótico (gentamicina, vancomicina e oxacilina), optou-se pela intervenção, vinte dias após a internação. Foi praticada excisão de uma vegetação única e do tecido valvar adjacente, na comissura ântero-posterior e plicatura anular. O resultado foi favorável, com cura clínica. O exame ecocardiográfico confirmou a presença da vegetação no pré-operatório e o funcionamento conservado da valva, após a plastia. O tratamento cirúrgico, com retirada do tecido infectado e preservação da valva constitui uma alternativa aplicável a certos casos de endocardite aguda das valvas atrioventriculares.
