We report a case of ulcerative colitis（UC）after mitral valve replacement（MVR）surgery due to infective endocarditis（IE). A 59-year-old woman underwent MVR for mitral regurgitation due to IE. Six days after the surgery, melena was observed suddenly, and she received a blood transfusion. Ulcer and erosion were observed in the rectum 5 to 10cm from the anal ring by endoscopy. We changed her antibiotic treatment and stopped warfarin potassium. Heparin sodium was started 2 days after melena. We diagnosed ulcerative colitis from the finding of the rectal lesion and biopsy. We gave mesalazine and betamethasone as treatment for UC. The patient’s condition improved and her general condition stabilized. She was discharged 36 days after surgery.
