【摘要】 目的 评价左心室造影对诊断特殊类型肥厚型心肌病的临床价值。方法 以心电图、超声心动图、冠状动脉造影及左心室造影等检查方法诊断21例特殊类型肥厚型心肌病。结果 21例心电图均显示相应导联的T波倒置,但只有8例患者达到对称深倒的标准;超声心动图只检出其中的9例患者符合局部肥厚型心肌病;左心室造影检出全部病例的局部心肌肥厚,18例诊断为心尖肥厚型心肌病,3例诊断为心室中部肥厚型心肌病,其中心尖肥厚型有11例呈左心室“黑桃”样改变。冠状动脉造影全部病例大致正常。结论 左心室造影在诊断特殊类型肥厚型心肌病中有重要价值,可明显提高该疾病的检出率。更多还原

【Abstract】 Objective To evaluate the value of left ventricular angiography in the diagnosis of special subtypical hypertrophic cardiomyopathy (HCM). Methods 21 cases of subtypical HCM were studied by electrocardiography(ECG), two-dimensional echocardography, left ventricular angiogram (LVG) and coronary angiography. Results ECG showed T wave inversion in related leads in 21 cases, but the amplitudes of inverted T wave≥1.0mV only in 8 cases; Echocardiography discoved hypertrophic local left ventricular wall in 8 cases. LVG demonstrated subtypical HCM with normal coronary angiography in all 21 cases (18 cases of apical HCM had the apical " spade" changes. Conclusion LVG is very helpful in the diagnosis of subtypical HCM with high sensitive and specificity.更多还原
