Acute endocarditis of the patch caused by Staphylococcus capitis in treated tetralogy of Fallot. An unusual location by an unusual bacterium.

摘要

We present the case of a 46 year-old male, HCV infected, treated with corrective surgery for tetralogy of Fallot (TOF) immediately after percutaneous closure of the Blalock Taussig shunt. Four months later, the patient had infective endocarditis by Staphylococcus capitis localised on the right side of the patch, treated by oxacillin and gentamycin. The particularity of our report is the unusual location of the acute endocarditis and the bacterium involved: the pulmonary valve is much more likely to be involved in endocarditis in TOF patients and the patch endocarditis has rarely been reported. Moreover, Staphylococcus capitis has never been reported as a cause of acute endocarditis in corrected TOF patients. We believe that antibiotic therapy should be instituted as soon as possible even though an aggressive surgical treatment is mandatory to achieve complete recovery, mainly when clinical condition and inflammation markers do not improve.
