Abstract
Background: Stenotrophomonas maltophilia (S. Maltophilia) is a gram-negative bacillus presumed to be a commensal and rarely causes opportunistic infections in immunocompromised individuals. Since it is resistant to most of the commonly prescribed antibiotics, it carries a high mortality. S. maltophilia infective endocarditis is extremely rare and only 43 cases have been reported worldwide till date.
Case Report: Our patient was a 45 years old male, known case of diabetes mellitus, Rheumatic heart disease (RHD) with previous aortic valve replacement, who had 2 episodes of S. maltophilia bacteremia and first episode being diagnosed as possible infective endocarditis being subsequently managed medically. However in the second episode of bacteremia diagnosis of infective endocarditis was confirmed and patient required prosthetic valve replacement.
Conclusion: This case is being presented to emphasize the possibility of infective endocarditis due to S. maltophilia and the clinicians should be aware of its potential significance in appropriate clinical setting and diagnosis should be considered early to prevent mortality.
Keywords: Stenotrophomonas Maltophilia, Infective Endocarditis.
