A case of bacterial endocarditis caused by Hemophilus aphrophilus is described, and 22 previously reported cases are reviewed. Eleven patients died and 12 survived; comparison of these two groups reveals that the patients who died were in the older population. The male/female ratio was 3.6:1. The organism was difficult to identify but had a wide range of in vitro bacteriologic sensitivities. This type of endocarditis is frequently associated with emboli and congestive heart failure; each occurred in 9 of 11 fatal cases and 3 of 12 nonfatal cases. Among the nonfatal cases, two patients had both emboli and congestive heart failure, requiring aortic valve replacement despite their precarious clinical condition. Initial drug therapy before results of antibiotic sensitivity tests are known should consist of penicillin combined with streptomycin. When emboli or congestive heart failure appears in Hemophilus aphrophilus endocarditis, early surgical intervention with valve replacement is indicated.
