Background the most common clinically presented valvular heart disease is mitral regurgitation (MR). Mitral valve repair is considered the surgery of choice for mitral regurgitation. Objective: The aim of the current work was to evaluate the early result of mitral repair with flexible and rigid annuloplasty devices in degenerative mitral regurgitation. Patients and Methods: This prospective study included a total of 64 patients with degenerative mitral regurgitation undergoing surgery for mitral valve repair with either a flexible or rigid annuloplasty device, attending at Department Cardiothoracic Surgery, Zagazig University Hospitals. This study was conducted between September 2017 and June 2020. We evaluated all patients after 6 months of surgery. Results: According to early mortality there were 2 patients in flexible group, and 1 patient in rigid one with no significant differences. There were also no significant differences according to failure of repair. Conclusion:It could be concluded that in spite of type of annuloplasty devices used, the early outcomes of mitral valve repair with rigid or flexible device show good results in our prospective study, but there were statistical differences between both groups regarding postoperative left ventricular dimension and function.
