    Abstract:
    We review the neurologic complications of 131 episodes of infective endocarditis, and the influences of some factors that are considered risk factors at its presentation, like the presence of vegetations detected by echocardiography, type and location of involved valve, or bacterial culture. Neurologic complications occurred in 28 patients (21.4%), 4 of them were excluded because of the absence of neuroimaging studies. In 21 patients the underlying cardiac pathology was valve disease and in the remaining 3 patients was congenital heart disease. 11 patients had native valve endocarditis and 10 prosthetic valve endocarditis. The cultured bacteria were Streptococcus viridans in 8 cases and Staphylococcus aureus in 7. The most frequent complication was cerebrovascular with incidence of cerebral embolism, and intracerebral hemorrhage of 62.5% and 8.3% respectively. Echocardiographic evidence of vegetation was seen in 18 patients, and cerebral embolism were noted in 12. Death occurred in 29% of patients with neurologic complications and 27% without. Two of nine patients who underwent open-heat surgery died. We conclude that there is no difference in the incidence of neurologic complications between mitral and aortic valve groups, neither when comparing native and prosthetic valve groups. Open-heart surgery does not increase mortality in this group of patients.
