Background And Aim Of The Study: Serious complications may occur after heart valve replacement, and many such patients will require reoperation. The study aim was to identify the pattern of tissue response around the sewing ring of those valves that have been explanted as a result of various valve-associated complications.
Methods: A total of 51 mechanical heart valves (MHVs) was explanted from 45 patients who had undergone reoperation for valve-related complications.
