Pacemaker lead endocarditis caused by Staphylococcus hominis.

Infective endocarditis related to pacemaker is a rare but serious condition in permanent venous tracing. A 65-year-old man was admitted to the hospital with high fever and chills. A DDD pacemaker had been implanted via the right subclavian vein because of sick sinus syndrome 6 years earlier. Transesophageal echocardiogram identified an oscillating round hyperechoic mass with a stalk near the tricuspid valve. Blood cultures grew Staphylococcus hominis. The patient was treated with antibiotics and operated on after the acute phase of the illness had subsided. We hereby report a case of lead endocarditis caused by S. hominis in a patient with pacemaker, which has been rarely reported in the English literature.
