Streptococcus suis is a zoonotic pathogen that causes invasive infections in humans. We report a case of aortic and tricuspid valve infective endocarditis caused by Streptococcus suis, which required cardiac surgery. The patient was a 53-year-old man with high fever and general fatigue for one month. He had been a pig farmer for 30 years. His blood cultures were positive for Streptococcus suis, and transthoracic echocardiography revealed aortic and tricuspid regurgitation with mobile vegetations adhering to the tricuspid valve. We performed aortic valve neo-cuspidization using autologous pericardium, and tricuspid valve replacement using a biological valve.
