摘　　要：目的探讨超声心动图诊断左室憩室的应用价值。方法对我院超声心动图诊断并经手术证实的4例左室憩室的超声及临床特点进行分析。结果先天性左室憩室的主要超声征象表现为突出于心脏室腔之外的囊性结构,囊腔入口起自于二尖瓣前叶根部与主动脉瓣环之间,囊腔位于升主动脉与左房之间。囊腔通过相对狭小的颈部与左室相通,且囊腔的运动与左室运动不同步。彩色多普勒示囊腔与左室之间有血流信号交通。4例患者均经手术证实并行憩室填充及封闭手术治疗。结论超声心动图是无创性、敏感诊断心室憩室的首选方法,在临床上可准确地对心室憩室与心室疝、室壁瘤和假性动脉瘤进行鉴别诊断。Objective To evaluate the value of echocardiography in the diagnosis of left ventricular diverticulum. Methods The characteristic of echocardiographic images were analyzed in 4 patients with left ventricular diverticulum which were confirmed by operation. Results The main characteristics of left ventricular diverticulum in echocardiography were as follows： cystoid accessory chamber out of heart arising from the intersection of mitral valve ring and aortic valve ring, just between ascending aorta and left atrium. It communicated with the main left ventricular chamber through an orifice. It was asynchronous or its motion was in contrast to the kinetics of the main chamber. The pulse and color Doppler echocardiography revealed that blood flow into the diverticulum in systole and out in diastole. The 4 patients received operations and the operative results were consistent with echocardiographic examination. Conclusions Echocardiography plays an important role in diagnosis of cardiac diverticulum and can also differentiate effectively cardiac diverticulum from ventricular herniation and ventricular aneurysm.
