Abstract

Objective

This study aimed to investigate the structure of the mitral valve in patients undergoing mitral valvuloplasty (MVP) using real-time three-dimensional transesophageal echocardiography (RT-3D-TEE). The main objective was to study the relationship between intraoperative annuloplasty ring size and mitral valve structure dimensions, with a focus on exploring the application value of RT-3D-TEE in MVP.

Methods

A total of 28 patients with degenerative mitral regurgitation (DMR), who underwent MVP between February and September 2022, as well as 12 normal control cases, were enrolled in this study. The MV annulus and leaflets were quantitatively analyzed using MVN software.

Results

The DMR group exhibited significantly greater dimensions in various parameters of the mitral valve, including the anterolateral-to-posteromedial diameter (D_AlPm), anterior-to-posterior diameter (D_AP), annulus height (H_A), three-dimensional annulus circumference (C_A3D), two-dimensional annulus area (AA_2D), anterior leaflet area (A_ant), posterior leaflet area (A_post), anterior leaflet length (L_ant), posterior leaflet length (L_post), and tenting volume (V_tent) compared to the control group.

Conclusion

Real-time three-dimensional transesophageal echocardiography provides valuable insights into the morphological structure of the mitral valve and lesion location. It can aid in surgical decision-making, validate the success of MVP, and potentially reduce mortality and complications associated with mitral valve repair procedures.

使用实时三维经食道超声心动图进行二尖瓣成形术

目的本研究旨在使用实时三维经食道超声心动图（RT-3D-TEE）研究接受二尖瓣成形术（MVP）患者的二尖瓣结构。主要目的是研究术中瓣环大小与二尖瓣结构尺寸之间的关系，重点探索 RT-3D-TEE 在 MVP 中的应用价值。方法本研究共纳入了 28 例在 2022 年 2 月至 9 月间接受 MVP 手术的退行性二尖瓣反流（DMR）患者和 12 例正常对照病例。使用 MVN 软件对二尖瓣瓣环和瓣叶进行定量分析。结果 DMR 组的二尖瓣各种参数，包括前外侧-后内侧直径（DAlPm）、前-后直径（DAP）、瓣环高度（HA）、三维瓣环周长（HA）、瓣环高度（HA）、瓣环周长（HA）均明显增大、与对照组相比，三维瓣环周长（CA3D）、二维瓣环面积（AA2D）、前瓣叶面积（Aant）、后瓣叶面积（Apost）、前瓣叶长度（Lant）、后瓣叶长度（Lpost）和瓣口容积（Vtent）均有显著差异。结论实时三维经食道超声心动图可提供有关二尖瓣形态结构和病变位置的宝贵信息。它有助于手术决策，验证 MVP 的成功，并有可能降低死亡率和与二尖瓣修复手术相关的并发症。

期刊介绍： The ANNALS OF NONINVASIVE ELECTROCARDIOLOGY (A.N.E) is an online only journal that incorporates ongoing advances in the clinical application and technology of traditional and new ECG-based techniques in the diagnosis and treatment of cardiac patients. ANE is the first journal in an evolving subspecialty that incorporates ongoing advances in the clinical application and technology of traditional and new ECG-based techniques in the diagnosis and treatment of cardiac patients. The publication includes topics related to 12-lead, exercise and high-resolution electrocardiography, arrhythmias, ischemia, repolarization phenomena, heart rate variability, circadian rhythms, bioengineering technology, signal-averaged ECGs, T-wave alternans and automatic external defibrillation. ANE publishes peer-reviewed articles of interest to clinicians and researchers in the field of noninvasive electrocardiology. Original research, clinical studies, state-of-the-art reviews, case reports, technical notes, and letters to the editors will be published to meet future demands in this field.
