A CASE OF MITRAL VALVE VEGETATION THAT COMPLETELY RESOLVED WITH ANTIBIOTIC TREATMENT
Abstract
A 48-year-old male teacher was admitted to thecardiology unit for evaluation of fever of 5 months'
duration. The fever was low grade associated with chills
and night sweats but no rigors. There were no systemic
complaints nor was any dental or other procedure
performed in the recent past. He was treated by many
general physicians with a variety of antibiotics and
antimalarial but there was no sustained response. He was
admitted to the general medical unit as a case of PUO and
thoroughly investigated but except for raised Erythrocyte
sedimentation rate (ESR) nothing was positive. He was
empirically started on Oflaxacin infusion but his fever did
not respond. Later he was started on anti TB drugs but
there was no response upto one month. Steroids were
added to the regimen but still no response.
He had sustained a myocardial infarction in 1986 and
1989 and had a Coronary artery bypass graft (CABG)
done in 1993, and was doing well with it. He was
reevaluated in cardiology with a temperature of 100°F. A
systemic exam only revealed soft systolic murmur at the
apex radiating to the axilla. All the investigations were
repeated and in addition echocardiography was
performed which was not done before. All the laboratory
test was negative again, and the echo showed mitral valve
vegetation. A diagnosis of possible infective endocarditis
was made and as the blood cultures were negative, he was
empirically started on Penicillin and gentamicin but there
was no response upto ten days. Echocardiography was
repeated that showed an increase in the size of vegetation
which was confirmed on transesophageal
echocardiography (Fig-1). The patient was switched over
to Ceftraixime, because of its better potency and broader
spectrum, l gram three times a day (TDS). On the 3rd day
his fever began to respond and he felt better two weeks
after initiation of Cefotaxime, TEE was repeated showing
complete resolution of vegetation. Treatment was
continued for another week and on a follow up a month
later he was found to have totally recovered and returned
to his job
