Abstract:
Objective To analyze abnormal characteristics of mitral valve (MV) caused by rheumatic and degenerative mitral valvedisease in virtue of the real-time three-dimensional transesophageal echocardiography(RT3DTEE) and quantitative analysis software.Methods Sixty patients underwent RT3DTEE study:21 patients with rheumatic valvular disease(RHD) studied intraoperatively(9 severe mitral stenosis,6 severe mitral regurgitation,6 severe mitral stenosis couple with regurgitation ) and 20 patients with normal MV who were used as controlsubjects(NS).TomTec-Arena 1.0-4D MV-Assessment 2.3 software was used to measure parameters of annular dimensions and geometry,[eafletsurface area and so on.Results Compared with NS,the diameter between anterior and posterior(AP) of RIID increased,however,the commissural width (CW)didn't change.Parameters of AP,CW,annulus circumference(AC) and annulus area(AA) of degenerative mitral valve disease(DMVD) increased obviously,the spherical index instead didn't change,the original "saddle" shapebecame flat.The impact on mitral valve leaflets is difference between RHD and DMVD.The anterior instead of posterior leaflet arena and length became larger of the group MS and MS&MI.However,the group of DMVD has increased leaflet area of anterior as well as posterior.Posterior leaflet angle is significantly increased in the group of MS&MI.The angle,between the DAP and plane of aortic valve annular (Angle AAo-AP),were magnified in both RHD and DMVD.From the automatic dynamic analysis,the parameters of annular displacement(max),annulus area fraction(2D)decreased considerably in RHD group.Conclusion RHD has relatively mild impact on annular of MV,but the lesions of mitral valve leaflet and chordae tendineae limit the movement of bicuspid valve an nular.The dilated and flattened annular of DMVD still has the "saddle" shape.
