An urgent surgery was initially performed to prevent further cerebral infarction, with abdominal surgery planned as the second stage. During the cardiac surgery, we observed a large defect following the partial resection of an infected posterior leaflet, and the adjacent calcified annulus was repaired using autologous pericardium.
