A 19-year-old woman, who had a recent extensive cerebral infarction caused by a septic embolization in the left-sided territory of the middle cerebral artery, successfully underwent mitral valve repair for severe mitral regurgitation caused by active infective endocarditis, 24 h after the onset of stroke. Anticoagulation during cardiopulmonary bypass was maintained with low-dose heparin and additional nafamostat mesilate. She had no further aggravation of the brain complication and recovered well with midterm mitral valve durability.
