The causes of mitral valve operation for patients who underwent aortic valve replacements (AVR)are rheumatic heart diseases, nonrheumatic insufficiency, infective endocarditis, prosthetic valve dysfunction and so on. No specific recommendation for surgical strategy of mitral valve surgery for those patients has been described and surgical strategy should be selected to each patient. The patients with rheumatic heart disease had higher risk for reoperation as compared with those with nonrheumatic heart disease and majority of patients with AVR who need reoperation because of mitral valve diseases had history of open or closed mitral commissurotomy. Therefore, mitral valve repair should be limited to lesions in which excellent durability of the repair can be expected to prevent re-operation.
