BACKGROUND: Infective endocarditis is a known complication of cardiac transplantation. However, published information has been limited to case reports and small case series. METHODS: Cardiac transplantation has been performed at Temple University Hospital since 1983. We identified transplant patients with ICD-9 codes for endocarditis or bacteremia. A diagnosis of endocarditis required fulfillment of the Duke criteria and presence of a vegetation. Clinical and microbiologic data were collected. Demographic and survival information were compared with heart transplant recipients without endocarditis. We reviewed all previously published cases using a MEDLINE search. RESULTS: Ten of 659 heart transplant recipients had endocarditis (1.5%, 187 cases per 100,000 person years). Mitral and tricuspid valves were involved predominantly. No patient had aortic valve infection. Patients with tricuspid valve infection had a greater median number of endomyocardial biopsies (n=23) than those with mitral valve infection (n=9, P=0.10). The major pathogens were Staphylococcus aureus (4 cases) and Aspergillus fumigatus (3 cases). Factors associated with S. aureus infection were new hemodialysis catheters, cellulitis, and a contaminated donor organ. All patients with A. fumigatus had antecedent cytomegalovirus viremia and disseminated fungal infection, including endophthalmitis. Endocarditis-related mortality was 80%. Median survival after transplant was 1.4 years in patients with endocarditis, compared with 9.3 years in other heart transplant recipients (P<0.001). CONCLUSIONS: Endocarditis is substantially more common in heart transplant recipients than in general populations. Frequent central venous catheter access and multiple endomyocardial biopsies appear to predispose to infection. Aspergillus is a common pathogen and endocarditis follows infection elsewhere. The prognosis of post-cardiac transplant endocarditis is poor.
