【摘要】：目的分析心脏人工机械瓣卡瓣患者的临床特点及超声心动图特征。方法回顾分析69例经手术证实的心脏人工机械瓣卡瓣患者的一般临床资料和超声心动图特征。结果 69例患者中,53.5%的患者症状表现为胸闷,50.7%的患者气短。人工机械瓣为单叶侧倾碟瓣者4例(5.8%),双叶侧倾碟瓣者65例(94.2%)。卡瓣瓣膜所占比例:二尖瓣47例(68.1%),主动脉瓣14例(20.3%),三尖瓣8例(11.6%)。卡瓣瓣膜最大流速范围分别为:二尖瓣(258.3±68.9)cm/s,主动脉瓣(483.0±77.6)cm/s,三尖瓣(200.0±17.0)cm/s。结论人工机械瓣卡瓣患者临床症状不典型,超声心动图二维能够观察确定是否有瓣膜活动不良,结合频谱多普勒测量流速及压力阶差可以进一步确诊,及时正确诊断有助于进行有效的治疗。
[Abstract]:Objective to analyze the clinical and echocardiographic features of patients with cardiac mechanical valve clamping. Methods the clinical data and echocardiographic features of 69 patients with cardiac mechanical valve were retrospectively analyzed. Results 53.5% of 69 patients showed shortness of breath in 53.5% of the patients. The maximum flow velocity ranges of mitral valve were 258.3 卤68.9 cm / s, aortic valve was 483.0 卤77.6 cm / s, tricuspid valve was 200.0 卤17.0 cm / s 路cm ~ (-1) respectively. Conclusion the clinical symptoms of patients with artificial mechanical valve entrapment are not typical, and the maximum velocity ranges of mitral valve, tricuspid valve, tricuspid valve and tricuspid valve are respectively 258.3 卤68.9 cm / s, 483.0 卤77.6 cm / s and 200.0 卤17.0 cm / s, respectively. Two dimensional echocardiography can be used to determine whether there is valve malactivity. The diagnosis can be further confirmed by using spectrum Doppler measurement of velocity and pressure step. Timely and correct diagnosis is helpful for effective treatment.
