This record contains raw data related to the article "Head to Head Comparison between Different 3-Dimensional Echocardiographic Rendering Tools in the Imaging of Percutaneous Edge-to-Edge Mitral Valve Repair" MitraClip (MC) is the most common percutaneous treatment for severe mitral regurgitation<br> (MR). An accurate two-dimensional and three-dimensional echocardiographic (3DTEE) imaging is<br> mandatory for the optimal procedural result. Recently transillumination 3DTEE rendering (3DTr) has<br> been introduced integrating a virtual light source into the dataset and with the addition of glass effect<br> (3DGl) allows to adjust tissue transparency improving depth perception and anatomical structure<br> delineation in comparison with the standard 3DTEE (3DSt). The aim of this retrospective study in<br> 30 patients undergoing MC, was to compare 3DSt, 3DTr, and 3DGl in mitral valve (MV) evaluation<br> and procedural result assessment. 3DTEE acquisitions obtained before and after MC were processed<br> with 3DSt, 3DTr, and 3DGl rendering. Each reconstruction was scored for quality and for ability<br> to recognize MV anatomy, MR origin, clip position, dimension and grasping. Imaging quality was<br> judged good or optimal in 52%, 76%, and 96% in 3DSt, 3DTr, and 3DGl reconstructions respectively.<br> In 26/30 patients a diagnostic incremental value was found with 3DTr vs. 3DSt and in 15/26 with<br> 3DGl vs. 3DTr and 3DSt. Only 3DGl with perpendicular cropping of the clip allowed to visualize and<br> measure the grasped portion of each mitral leaflets. 3DTEE imaging during MC may be improved<br> by 3DTr and 3DGl providing a better evaluation of MV, of leaflet grasping and of residual MR jets<br> after MC.
