| Popis: | Background Endocarditis complicating central venous catheter blood stream infection (CVC-BSI) is a serious complication and is being seen with increasing frequency. Methods All patients discharged from our institution with International Classification of Disease (ICD-9) codes of endocarditis and CVC-BSI were identified. The medical records of those meeting our inclusion criteria were reviewed. Results From October 1, 1998 until December 31, 2006, 24 patients were identified with inpatient mortality of 20.8%. Nine cases were nosocomial and 15 were non-nosocomial. The most common comorbidities were diabetes mellitus (45.8%), chronic kidney disease (58.4%), prior valvular abnormalities (37.5%), and multiple prior hospitalizations (65.2%). There were 13 external lines, 9 tunneled lines, and 2 implantable ports. Responsible microorganisms included Staphylococcus aureus in 54.6%, coagulase-negative staphylococci in 37.5%, Candida species (spp.) in 16.6%, and enterococci in 12.5%. Five cases were polymicrobial. The line tip was within the right atrium (RA) in 37.5%, the superior vena cava (SVC)-RA junction in 20.8%, the SVC in 33.3%, and the pulmonary artery in 4.2% of patients. Sites of endocardial involvement were the aortic valve in 6 patients, mitral valve in 7 patients, tricuspid valve in 6 patients, right atrial wall in 11 patients, and pacemaker wire in 2 patients. Isolated right-sided involvement occurred in 50% of cases, isolated left-sided in 33.4%, and bilateral involvement in 16.6%. Transesophageal echocardiography (TEE) was necessary for diagnosis in 10 cases (41.6%). Conclusions Endocarditis complicating CVC-BSI more often involves right-sided structures, with catheter tips in or near the right atrium, frequently requires TEE for diagnosis, and has significant inpatient mortality.
