The arteriovenous shunt (AVS) is the most commonly used vascular access in patients receiving regular haemodialysis. The AVS may have a significant haemodynamic impact on patients with heart failure. Many studies have sought to understand the effect of AVS creation or closure on heart structure and functions, most of which use non-invasive methods, such as echocardiography or cardiac MRI. Data are mainly focused on heart failure with reduced ejection fraction and there are limited data on heart failure with preserved ejection fraction. The presence of an AVS has a significant haemodynamic impact on the cardiovascular system and it is a common cause of high-output cardiac failure. Given that most studies to date use non-invasive methods, invasive assessment of the haemodynamic effects of the AVS using a right heart catheter may provide additional valuable information.
动静脉分流（AVS）是接受定期血液透析患者最常用的血管通路。AVS可能对心力衰竭患者产生显著的血流动力学影响。许多研究试图了解建立或闭合AVS对心脏结构和功能的影响，其中大多数使用非侵入性方法，如超声心动图或心脏磁共振成像。数据主要集中在射血分数降低的心力衰竭患者，而关于射血分数保留的心力衰竭患者的数据有限。AVS的存在对心血管系统有显著的血流动力学影响，是高输出量心力衰竭的常见原因。鉴于迄今为止大多数研究使用非侵入性方法，使用右心导管对AVS的血流动力学效应进行侵入性评估可能会提供额外的有价值信息。
