title: Staphylococcus aureus bacteremia and endocarditis associated with a removable infected intravenous device.
abstract: Records of 21 patients with Staphylococcus aureus bacteremia associated with a removable infected intravenous device were reviewed. Sixteen patients had a peripheral intravenous catheter, four had a central venous catheter and one had a transvenous cardiac pacer. The duration of the indwelling intravenous device in situ prior to the detection of infection ranged from two to 11 (mean 5.2) days. The infected intravenous device was promptly removed as soon as bacteremia was suspected. Endocarditis was diagnosed in eight patients: in two patients an aortic murmur developed; in two the diagnosis was made clinically and was confirmed at necropsy (one mitral and one aortic); in four the diagnosis was made at necropsy (two tricuspid and two atrial wall). In patients with Staph. aureus bacteremia associated with a removable infected intravenous device, the risk of endocarditis developing was significant.
