Abstract：Objective To evaluate the clinical value of real-time three-dimensional transesophageal echocardiography in mitral valve prolapse associated with infective endocarditis.Methods 20 patients undergoing mitral valve prolapse combined with IE were selected to undergo transthoracic echocardiography(TTE) and RT-3D-TEE.The prolapse position and performance characteristics were analyzed and intraoperative findings were compared.Results (1)The sensitivity of RT-3D-TEE and TTE in mitral valve prolapse was 90.3％ and 87.1％,the specificity was 97.8％ and 97.8％,the positive predictive value was 93.3％ and 93.1％,the negative predictive value was 96.7％ and 95.6％,The total compliance rate was 95.8％ and 95％,RT-3D-TEE parameters were higher than TTE.(2)The diagnostic sensitivity and specificity of RT-3D-TEE in mitral valve formation,chordae rupture and perforation were higher than those in TTE.Conclusion (1)RT-3D-TEE is more accurate than TTE in locating the location of mitral valve prolapse.(2)RT-3D-TEE can accurately display the various manifestations of IE,and it is an important guide to the choice of preoperative surgical methods.
