A Multidisciplinary Approach to Triple-Valve Infective Endocarditis With Multi-Organ Involvement.

Multivalvular endocarditis is a rare and potentially fatal complication that can occur in people who inject drugs. Currently, there are few cases that have been studied or reported in literature. A complication of this manifestation that worsens prognosis and treatment is the distribution of septic emboli throughout the body which highlights the dissemination of the infection. There are no specific guidelines on the treatment of multivalvular endocarditis, but its complexity can present challenges in administering medical and surgical treatment. In this case of a 37-year-old man with infective endocarditis of 3 valves, a comprehensive work-up found septic emboli in the lungs, kidneys, ribs, spine, and brain with ophthalmologic involvement that resulted in visual impairment. This case highlights important complications that can occur with septic emboli and management of these issues using a multidisciplinary approach including the treatment of substance use disorder.
