The first article, Changes in Mitral Regurgitation After Replacement of the Stenotic Aortic Valve (2008) stresses a relatively large patient study of those undergoing Aortic valve replacement and then possibly experiencing mitral regurgitation (MR), a common and sometimes concerning complication that as the study shows can occur without any known mitral defect. The study is significant in that it establishes the fact that MR is not as dangerous as once thought and can be resolved without further surgical intervention in many patients, where as in the past further surgical intervention was the most likely outcome. The study also indicated certain precursors or markers that allows the initial surgical screening of patients who would benefit from mitral surgery, prior to mitral failure and could therefore receive the procedure during the initial surgical intervention, rather than as a separate surgical event. It is clear that the common sense of this study is...
