Abstract Background Rheumatic mitral valvular disease is more common than degenerative mitral valve disease. Mitral valve repair is not possible in large number of patients because of rheumatic cicatrized subvalvular mitral valve disease. The prosthetic mitral valve replacement is commonly performed in our center. Objective The aim of the study was to evaluate and assess the short outcome of Mitral Valve Replacement with or without Tricuspid Valve Repair. Patients and Methods This study was done in department of Cardiothoracic surgery, Faculty of Medicine at Ain Shams university, after approval of the local ethical committee from 2015 to 2016.The inclusion criteria includes All gender, All age, Primary Mitral valve replacement for severe Mitral valve disease of Rheumatic origin with or without Tricuspid Valve Repair and Primary Mitral valve replacement for severe Mitral valve disease of Degenerative origin with or without Tricuspid Valve Repair and the exclusion criteria includes concomitant coronary artery bypass graft surgery or other cardiac operations or infective endocarditis and Patients with chronic liver, kidney and parenchymal pulmonary disease. Results This study included one hundred and seventy- seven (177) patients; One hundred and thirty one (131) patients did Mitral Valve Replacement without Tricuspid valve Repair, Fourty six (46) patients did Mitral valve Replacement with Tricuspid valve Repair and the outcome was Mortality (3.9%), Reoperaion (5.08%), Stroke (0. 56%), Re-Intubation (1.13%) and Re-Admission to ICU (1.69%) Conclusion The Reoperation has a direct relation and effect on the Mortality,Prolonged bypass time independently predicts postoperative morbidity and mortality and Prolonged aortic cross-clamp time significantly correlates with major post-operative morbidity and mortality.

Background 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 patient-prosthesis mismatch. Methods A prospective study was conducted on 715 patients with a mean age of 42 ± 11 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 cm2·m−2. The mean clinical and echocardiographic follow-up was 26.74 ± 11.58 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 (<27 mm) was inserted in 54.3%. Mortality during follow-up was 9% (65 patients). Patient-prosthesis mismatch was identified in patients with preoperative rheumatic mitral valve pathology, associated tricuspid regurgitation, higher New York Heart Association class, preoperative atrial fibrillation, mitral stenosis, and small preoperative left ventricular dimensions. Multivariate analysis identified mitral stenosis, preoperative atrial fibrillation, and small postoperative left ventricular end-diastolic dimension as risk factors for patient-prosthesis mismatch. Conclusion Patient-prosthesis mismatch is a common sequela after mechanical mitral valve replacement. Identification of predictors of patient-prosthesis mismatch can help so that a preoperative strategy can be implemented to avoid its occurrence.
