摘　　要：目的探究冠脉CT与超声心动图对主动脉瓣关闭不全左心室功能的诊断价值。方法选取2017年4月至2019年6月我院影像科诊治的85例主动脉瓣关闭不全患者进行研究。患者均进行冠脉CT与超声心动图检查,以手术病理结果为“金标准”,评估冠脉CT与超声心动图的诊断价值。结果超声心动图诊断主动脉瓣关闭不全左心室功能总准确率为70.59%,超声心动图诊断结果与“金标准”Kappa值为0.184,P﹤0.001;冠脉CT诊断主动脉瓣关闭不全左心室功能总准确率为83.53%,冠脉CT诊断结果与金标准Kappa值为0.478,P﹤0.001;两种方式联合诊断主动脉瓣关闭不全左心室功能总准确率为90.59%,两种方式联合诊断与“金标准”Kappa值为0.640,P﹤0.001;两者联合诊断主动脉瓣关闭不全左心室功能与“金标准”的一致性优于单纯的冠脉CT与超声心动图。结论冠脉CT与超声心动图对主动脉瓣关闭不全左心室功能诊断准确率较高,优于单纯应用冠脉CT与超声心动图检查。Objective To investigate the diagnostic value of coronary CT and echocardiography for left ventricular function in aortic valve insufficiency.Methods A total of 85 patients with aortic valve insufficiency diagnosed and treated in the imaging department of our hospital from April 2017 to June 2019were enrolled and underwent coronary CT and echocardiography.The diagnostic value of coronary CT and echocardiography was evaluated with the surgical pathological results as the gold standard.Results The total accuracy of left ventricular function in the diagnosis of aortic valve insufficiency by echocardiography was 70.59%,and the Kappa value of the echocardiographic diagnosis and the gold standard was 0.184,P﹤0.001;the total accuracy was 83.53%by coronary CT,and the Kappa value of coronary CT and the gold standard was 0.478,P﹤0.001;the total accuracy was 90.59%by those two methods combined,andthe standard Kappa value was 0.640,P﹤0.001.The agreement of two methods combined was better than that of coronary CT and echocardiography alone.Conclusion Coronary CT with echocardiography is more accurate in diagnosing left ventricular function in aortic valve insufficiency,which is better than coronary CT and echocardiography alone.
