Native quadruple-valve endocarditis caused by Enterococcus faecalis.

Abstract

We report the case of a patient with postoperative, hospital-acquired, quadruple-valve endocarditis caused by Enterococcus faecalis on presumed normal native valves. During a cervical laminectomy, the patient had a non-ST-elevation myocardial infarction that was treated conservatively. In the intensive care unit, the patient became febrile and developed a new 2/6 systolic murmur. Blood cultures grew E. faecalis, and the patient was given antibiotics. Postoperative transthoracic echocardiography and transesophageal echocardiography revealed vegetations on all 4 heart valves. Subsequently, the patient was moved to another facility and died. No autopsy was performed. E. faecalis is the third-most-common cause of bacterial endocarditis overall; however, it is rarely found in multiple-valve, hospital-acquired endocarditis. Although transthoracic echocardiography is a powerful diagnostic tool, transesophageal echocardiography increases the sensitivity and specificity to about 90%. In our patient, the diagnosis of native quadruple-valve endocarditis would not have not been made without the use of transesophageal echocardiography.
