摘　　要：二尖瓣反流(MR)促进左室(LV)扩张和离心性重构。在存在LV运动不同步和心力衰竭的情况下,心脏再同步化治疗可减轻MR的严重程度。但是,原发性MR是否可引起LV运动不同步尚不清楚。作者观察了在存在LV扩张且射血分数(EF)>55%的情况下,中至重度原发性MR是否可引起LV运动不同步。纳入了37例正常受试者和22例无冠状动脉疾病的中至重度原发性MR患者,Mitral regurgitation(MR) promotes left ventricular(LV) dilatation and eccentric remodeling. In the presence of LV dyssynchrony and heart failure, cardiac resynchronization therapy decreases the severity of MR. Whether primary MR can cause LV dyssynchrony is unknown. We investigated whether moderate to severe primary MR causes LV dyssynchrony in the presence of LV dilation and an ejection fraction(EF) >55% . We studied 37 normal subjects and 22 patients with moderate to severe MR and no coronary artery di...
