| Abstract: |
Patient-prosthesis mismatch after mitral valve replacement has an unfavorable postoperative hemodynamic outcome, which underlines the importance of identifying and preventing prosthesis- and patient-related risk factors. This study was conducted to determine the incidence and identify possible predictors of patientprosthesis mismatch. Methods: A prospective study was conducted on 715 patients with a mean age of 4211 years who underwent mechanical mitral valve replacement between 2013 and 2017. The effective orifice area of the prostheses was estimated by the continuity equation, and a mismatch was defined as an effective orifice area index 1.2 cm2m 2. The mean clinical and echocardiographic follow-up was 26.7411.58 months. Multivariate regression analysis was performed to identify predictors of patient-prosthesis mismatch. Results: Patient-prosthesis mismatch was detected in 382 (53.4%) patients. A small mechanical prosthesis ( |
