二尖瓣置换术后左心房功能的研究进展

Research Progress of Left Atrial Function af-ter Mitral Valve Replacement

摘要: 二尖瓣疾病是一种常见的心脏瓣膜疾病，并且在各组年龄段中都很普遍，大多由风湿热所造成，具有显著的发病率和死亡率。二尖瓣疾病的类型包括二尖瓣反流和二尖瓣狭窄。超声心动图仍然是诊断的主要方式，建议结合多个参数进行综合评估。目前，二尖瓣疾病常用二尖瓣置换术治疗，能有效延长患者生命，恢复患者的心功能。近年来随着对左心房的研究逐渐深入，已证实左心房功能的变化能有效地评估心脏瓣膜病患者术后临床疗效及预后。本文对二尖瓣置换术后患者左心房结构及功能变化的研究进行综述。

Abstract: Mitral valve disease is a common heart valve disease, and is common in all age groups, mostly caused by rheumatic fever, with significant morbidity and mortality. Types of mitral valve disease include mitral regurgitation and mitral stenosis. Echocardiography is still the primary mode of di-agnosis, and comprehensive evaluation with multiple parameters is recommended. At present, mi-tral valve replacement is commonly used in the treatment of mitral valve disease, which can effec-tively prolong the life of patients and restore the heart function of patients. In recent years, with the gradual deepening of research on the left atrium, it has been proved that the changes in the func-tion of the left atrium can effectively evaluate the clinical efficacy and prognosis of patients with valvular heart disease after surgery. This article reviews the changes of left atrium structure and function after mitral valve replacement.
