Abstract

This pilot study aimed to develop a new, reliable, and easy-to-use method for the evaluation of diastolic function through the M-mode measurement of mitral valve (MV) movement in the parasternal long axis (PSLA), similar to E-point septal separation (EPSS) used for systolic function estimation. Thirty healthy volunteers from a tertiary emergency department (ED) underwent M-mode measurements of the MV anterior leaflet in the PSLA view. EPSS, A-point septal separation (APSS), A-point opening length (APOL), and E-point opening length (EPOL) were measured in the PSLA view, along with the E and A velocities and e' velocity in the apical four-chamber view. Correlation analyses were performed to assess the relationship between M-mode and Doppler measurements, and the measurement time was evaluated. No significant correlations were found between M-mode and Doppler measurements in the study. However, M-mode measurements exhibited high reproducibility and faster acquisition, and the EPOL value consistently exceeded the APOL value, resembling the E and A pattern. These findings suggest that visually assessing the M-mode pattern on the MV anterior leaflet in the PSLA view may be a practical approach to estimating diastolic function in the ED. Further investigations with a larger and more diverse patient population are needed to validate these findings.

摘要

这项初步研究旨在开发一种新的、可靠且易于使用的方法，通过在胸骨旁长轴（PSLA）视图中对二尖瓣（MV）运动进行M型测量来评估舒张功能，类似于用于评估收缩功能的E点室间隔分离（EPSS）。来自一家三级急诊科（ED）的30名健康志愿者在PSLA视图下接受了MV前叶的M型测量。在PSLA视图中测量了EPSS、A点室间隔分离（APSS）、A点开口长度（APOL）和E点开口长度（EPOL），同时在心尖四腔视图中测量了E和A速度以及e'速度。进行相关性分析以评估M型测量与多普勒测量之间的关系，并对测量时间进行了评估。在该研究中，未发现M型测量与多普勒测量之间存在显著相关性。然而，M型测量具有高重复性且采集速度更快，并且EPOL值始终超过APOL值，类似于E和A模式。这些发现表明，在PSLA视图中目视评估MV前叶的M型模式可能是在急诊科评估舒张功能的一种实用方法。需要对更大且更多样化的患者群体进行进一步研究以验证这些发现。
