All patients underwent valvular surgical procedures including mitral valve replacement (MVR), aortic valve replacement (AVR), AVR with coronary artery bypass grafting (CABG), MVR with CABG, or AVR and MVR with or without CABG. This study included patients who underwent surgery between 2002 and 2017.Results: Three hundred and forty-six patients were included in this study. The mean patient age was 51.6± 16.1 years; 37% of the patients underwent AVR, 28% underwent MVR, and 13% underwent a combination of MVR with AVR, AVR with CABG in 6%, and MVR with CABG in 10%. The operative mortality rate was 5.8% (n=20). Univariate analysis revealed that the predictors of mortality included age (P 4 cm was found to strongly predict mortality after rheumatic heart valve surgery.Keywords: valve surgery, mortality, mitral, aortic, left atrial size
