Methicillin-resistant Staphylococcus aureus endocarditis following repair of tetralogy of Fallot.

Infectious endocarditis following cardiac surgery, particularly that caused by methicillin-resistant Staphylococcus, aureus is a rare and highly lethal complication. We report a case of a 2-year-old girl who developed methicillin-resistant S. aureus endocarditis and mediastinitis following the intracardiac repair of tetralogy of Fallot using Dacron patches. The patient enveloped severe bacteremia accompanied by disseminated intravascular coagulation and progressive enlargement of vegetation. Despite this condition, the patient was successfully treated by repair using double autogenous pericardial patches. Aggressive removal of foreign material and replacement with autogenous tissue resulted in a favorable outcome.
