摘要
目的探讨左室超声造影在诊断左室心肌致密化不全中的应用价值。方法对10例经胸超声心动图初步诊断和疑似的心肌致密化不全患者进行左室超声造影检查，进一步观察左室内过度增生的肌小梁的范围、心内膜连续性、致密心肌厚度及造影剂在小梁隐窝内充盈情况。结果左室超声造影可更加清晰地观察到非致密心肌的范围，造影剂在小梁间隙和隐窝内充盈，超声造影对致密心肌厚度的测量更为精确、客观。结论左室超声造影可用于诊断左室心肌致密化不全，是对常规经胸超声心动图的良好补充。
Objective To assess the usefulness of left ventricular contrast echocardiography in diagnosis of left ventricular myocardium noncompaction. Methods Contrast echocardiography was done in ten patients who were diagnosed or suspected with left ventricular noncompaction by common transthoracic echocardiography, for further study of the trabecular muscles extent, the continuity of the endocardium, the compact myocardium thickness, and the contrast agent in the trabecula recessus. Results By contrast echocardiography, noncompaction myocardium thickness can be perspicuously observed, the turgot of the contrast agent was vividly detected in the trabecular recessus. Especially for the measurement of compaction myocardium, the contrast echocardiography was more accurate than in the condition of the common echocardiography. Conclusions Left ventricular contrast echocardiography can be used in the diagnosis of left ventricular noncompaction,it was a good added method of conventional echocardiography.
