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.本数据集包含与论文《不同三维经食管超声心动图（3DTEE）渲染工具在经导管缘对缘二尖瓣修复术成像中的头对头比较》相关的原始数据。二尖瓣夹合器（MitraClip，MC）是治疗重度二尖瓣反流（MR）最常用的经导管干预手段。获取精准的二维及三维经食管超声心动图（3DTEE）影像，是实现最优手术结局的必备前提。 近期，透照型三维经食管超声心动图渲染（3DTr）技术问世，该技术将虚拟光源整合至影像数据集；搭配玻璃效应渲染（3DGl）模式时，可调节组织透明度，相较标准三维经食管超声心动图渲染（3DSt），能够有效改善深度感知与解剖结构的辨识度。 本回顾性研究纳入30例行MC手术的患者，旨在对比3DSt、3DTr及3DGl三种渲染方式在二尖瓣（MV）评估与手术效果评估中的应用价值。MC手术前后获取的3DTEE影像，分别通过3DSt、3DTr及3DGl三种方式完成渲染重建。对每一例重建结果的影像质量，以及识别二尖瓣解剖结构、MR起源、夹合器位置、尺寸及夹合效果的能力进行评分。 3DSt、3DTr及3DGl重建影像的质量被评为良好或最优的比例分别为52%、76%及96%。相较于3DSt，3DTr在26/30例患者中体现出诊断增量价值；而相较于3DSt与3DTr，3DGl在15/26例患者中体现出诊断增量价值。仅3DGl搭配夹合器垂直裁剪功能，可可视化并测量每一处二尖瓣瓣叶的夹合区域。 经导管缘对缘二尖瓣修复术中的3DTEE影像，可通过3DTr与3DGl得到优化，从而实现对二尖瓣、瓣叶夹合效果以及术后残余MR反流束的更精准评估。
