Abstract

© Author(s) (or their employer(s)) 2022. No commercial reuse. See rights and permissions. Published by BMJ. INTRODUCTION Acute native valve aortic regurgitation (AR) is a rapidly fatal condition resulting from the sudden loss of valve competency. Acute AR requires prompt intervention yet often is missed because the clinical presentation is not recognised. The large volume of retrograde diastolic flow into a left ventricle (LV) without compensatory dilation results in an abrupt decrease in cardiac output and increase in LV enddiastolic pressure (figure 1). Urgent surgical intervention to restore valve competency and treat the underlying cause is essential. Options for medical stabilisation or palliative care are limited. This review covers the aetiology, haemodynamics, clinical presentation, diagnosis, medical stabilisation and surgical management of patients with acute native valve AR.
急性主动脉瓣反流的临床表现、诊断和处理
©作者(或其雇主)2022。禁止商业重用。请参阅权利和权限。英国医学杂志出版。摘要急性主动脉瓣返流(Acute native valve aortic reflux, AR)是由主动脉瓣功能突然丧失引起的一种迅速致命的疾病。急性AR需要及时干预,但往往被错过,因为临床表现不确定。无代偿性扩张的大量逆行舒张血流进入左心室(LV)导致心输出量突然下降和左室舒张压升高(图1)。紧急手术干预以恢复瓣膜功能并治疗根本原因是必要的。医疗稳定或姑息治疗的选择有限。本文综述了急性本源性瓣膜AR患者的病因学、血流动力学、临床表现、诊断、医疗稳定和手术治疗。
