摘　　要：目的　评价经胸和食道超声心动图诊断老年人主动脉瓣周钙化的价值及其临床意义。方法　完成全部检查者共 5 0例 ,其中男性 2 4例 ,女性 2 6例 ,自身前后对照 ,每位入选对象先后接受经胸超声心动图 (TTE)、经食道超声心动图 (TEE)检查和螺旋CT检查各一次。结果　螺旋CT示瓣周钙化阳性 19例 ,阴性 31例。以螺旋CT为对照 ,TTE的敏感性为 6 3% ,特异性为 71% ,准确性为 6 8% ;TEE的敏感性为 79% ,特异性为 6 5 % ,准确性为 70 % ;联合检查的敏感性为 84 % ,特异性为 5 8% ,准确性为 6 8%。螺旋CT阳性组高血压发病率显著高于阴性组 (P <0 0 5 )。结论　三种检查方法比较 ,差异均有显著性意义(P <0 0 1)。以螺旋CT为对照 ,TEE诊断早期老年性主动脉瓣周钙化的敏感性显著高于TTE 。Objective To evaluate the value of transthoracic(TTE) and transesophageal echocardiography(TEE) in detecting the calcification.Methods Fifty-five patients were enrolled in the self-control study.Each subject was performed TTE,TEE and spiral CT respectively.Result There was significant difference between TTE and TEE in detecting the calcification at the base of aortic valve leaflet(P<0.01).The sensitivity of transthoracic echocardiography was 63%,specificity was 71%,and accuracy was 68%.The sensitivity,specificity and accuracy of transesophageal echocardiography was 79%,65%,70%,respectively.The incidence of hypertension was higher in positive spiral CT(P<0.05).Conclusion The sensitivity of TEE is higher than that of TTE in the diagnosis of early senile degenerative valvular disease.The sensitivity of parallel test by combining transthoracic echocardiography with transesographgeal echocardiography is 84%,the specificity 58%,and the accuracy 68%.
