Klebsiella oxytoca endocarditis is extremely rare, with only 4 cases of isolated K oxytoca endocarditis reported in the literature. We report a case of K oxytoca endocarditis in a patient with a bioprosthetic aortic valve. We also discuss that physicians should consider K pneumoniae and K oxytoca endocarditis as separate entities to be managed differently. We highlight that K oxytoca responds to antibiotic therapy alone, unlike the need for surgical intervention in K pneumoniae endocarditis.
