Cardiac valve replacement in patients infected with the human immunodeficiency virus.

Abstract

Major surgical procedures, especially when performed under general anesthesia, can depress immunological parameters measured in vitro. Therefore concern has been expressed that operation might have an adverse effect on the immune status of individuals infected with the human immunodeficiency virus (HIV). Four HIV-positive patients without symptoms of HIV disease underwent cardiac valve replacement in consequence of infective endocarditis. After up to 15 months postoperatively, 3 patients are alive and well without signs of progressive immunodeficiency or recurrent endocarditis. One patient died of recurrent endocarditis without evidence of HIV-related disease on autopsy. Cardiac operation does not seem to accelerate HIV-related immunodeficiency.
