Comparison of pre and post operative echo changes after mitral valve replacement with cardiothoracic vascular surgery


Tej Karan Saini, Rajesh Sharma, Praveen Kumar Singhal, Rajkumar Yadav

Background: There is a scarcity of information on the impact of mitral valve (MV) replacement on LA size. The goal of this study was to assess changes in LA volumes after MV replacement using real-time 3-D echocardiography. Methods: A total of 50 patients with severe mitral regurgitation caused by MV prolapse who were planned for early treatment were included in the study. Real-time 3-dimensional echocardiography was used to assess LA volumes prior to the surgery (maximum, before atrial active contraction [preA], and minimum). The same assessment was carried out six months and one year after the MV replacement. As a control group, twenty healthy volunteers were enlisted who were age and gender matched. Results: Patients had significantly greater LA volumes before MV replacement than controls. LA volumes fell considerably six months after the operation with a further decline at one year, resulting in values similar to controls. Age (r = 0.42) and postoperative transmitral mean pressure gradient (r = 0.32) were shown to be inversely associated to the amount of LA reverse remodelling, although a positive correlation was found. Conclusion: When performed early, MV replacement resulted in considerable LA reverse remodelling in patients with severe mitral regurgitation due to MV prolapse.
