Purpose of Review

Although rare, the development of mechanical complications following an acute myocardial infarction is associated with a high morbidity and mortality. Here, we review the clinical features, diagnostic strategy, and treatment options for each of the mechanical complications, with a focus on the role of echocardiography.

Recent Findings

The growth of percutaneous structural interventions worldwide has given rise to new non-surgical options for management of mechanical complications. As such, select patients may benefit from a novel use of these established treatment methods.

Summary

A thorough understanding of the two-dimensional, three-dimensional, color Doppler, and spectral Doppler findings for each mechanical complication is essential in recognizing major causes of hemodynamic decompensation after an acute myocardial infarction. Thereafter, echocardiography can aid in the selection and maintenance of mechanical circulatory support and potentially facilitate the use of a percutaneous intervention.

超声心动图在急性心肌梗死机械并发症的识别和治疗中的应用

审查目的

尽管罕见，但急性心肌梗塞后机械并发症的发生与高发病率和死亡率相关。在这里，我们回顾每种机械并发症的临床特征、诊断策略和治疗方案，重点关注超声心动图的作用。

最近的发现

全球经皮结构介入治疗的发展为机械并发症的治疗带来了新的非手术选择。因此，特定的患者可能会受益于这些已建立的治疗方法的新用途。

概括

彻底了解每种机械并发症的二维、三维、彩色多普勒和频谱多普勒结果对于识别急性心肌梗死后血流动力学失代偿的主要原因至关重要。此后，超声心动图可以帮助选择和维持机械循环支持，并有可能促进经皮介入的使用。
