Supplementary Material for: Pivotal Role of Bedside Doppler Echocardiography in the Assessment of Patients with Acute Heart Failure and Mitral Regurgitation

Patients presenting with mitral regurgitation and acute heart failure remain a challenge for the clinicians. Bedside echocardiography ascertains the functional or primary nature of mitral regurgitation, thereby allowing to focus therapy on the left ventricle and mitral valve apparatus in patients with functional mitral regurgitation and to hasten mitral valve repair or replacement when acute heart failure results from primary mitral regurgitation. This short article reviews the evaluation by bedside echocardiography to guide management of these patients.

伴二尖瓣反流（mitral regurgitation）与急性心力衰竭的患者，始终是临床医师面临的诊疗挑战。床旁超声心动图（bedside echocardiography）可明确二尖瓣反流的功能性或原发性分型，进而指导针对性治疗：对于功能性二尖瓣反流（functional mitral regurgitation）患者，将治疗重心置于左心室与二尖瓣装置；而对于因原发性二尖瓣反流引发急性心力衰竭的患者，则可加快推进二尖瓣修复或置换手术。本文综述了床旁超声心动图的评估手段，以指导该类患者的临床管理。
