Introduction: The aim of this study was to investigate the effects of patient prosthesis mismatch on functional mitral regurgitation after mechanical aortic valve replacement. Patients and Methods: Total 59 patients were enrolled. All the echocardiographic assessments were performed by a single cardiologist. The patients were divided into two subgroups as per the presence of patient prosthesis mismatch. Group 1 comprised patients with mismatch, and group 2 included those without mismatch. Results: There were no significant differences between the two groups in terms of postoperative mitral regurgitation development, postoperative left ventricular mass regression, postoperative pulmonary arterial pressure, and postoperative functional capacity. Conclusion: Patient prosthesis mismatch is not a predictive factor for the development of functional mitral regurgitation after mechanical aortic valve replacement.
