Purpose of Review

The aim of this study is to review current echocardiographic modalities utilized in the assessment of the preoperative liver transplant candidate with an emphasis on newer techniques. We sought to assess if newer methods imparted additional diagnostic or prognostic accuracy compared to prior methods based on existing studies.

Recent Findings

Standard dobutamine stress echocardiography offers important information regarding operative risk and post-operative survival in liver transplant candidates; however, technologies such as speckle-tracking echocardiography (STE) and evaluation of diastolic function have emerged as useful tools as well.

Summary

2D-STE and diastolic echocardiography offer additional parameters such as global longitudinal strain and measures of diastolic dysfunction that can better predict peri-operative and post-operative complications in liver transplant candidates. If able, practitioners should utilize these methods routinely in their assessment of liver transplant candidates.

肝移植患者的超声心动图

审查目的

本研究的目的是回顾当前用于评估术前肝移植候选者的超声心动图模式，重点是更新技术。我们试图评估与基于现有研究的先前方法相比，新方法是否具有额外的诊断或预后准确性。

最近的发现

标准多巴酚丁胺负荷超声心动图可提供有关肝移植候选者的手术风险和术后生存率的重要信息；然而，斑点跟踪超声心动图 (STE) 和舒张功能评估等技术也已成为有用的工具。

概括

2D-STE 和舒张超声心动图提供了额外的参数，例如整体纵向应变和舒张功能障碍的测量，可以更好地预测肝移植候选者的围手术期和术后并发症。如果可能，从业者应在评估肝移植候选者时常规使用这些方法。
