摘要
目的 探讨经胸超声心动图 (TTE)和多平面经食管超声心动图 (MTEE)诊断主动脉瓣感染性心内膜炎 (AVIE)伴主动脉瓣穿孔 (AVP)的价值。方法 对 10例经TTE或 (和 )MTEE诊断的AVIE并发AVP患者的超声心动图资料进行分析 ,将超声特点与手术结果进行对照。结果 TTE或MTEE诊断AVIE并AVP的要点为二维超声心动图显示瓣体的回声连续中断或缺失 ,彩色多普勒血流显像显示瓣体回声缺失部位穿瓣偏心血流 ,其特异性为 10 0 % ,敏感性为 90 .9%。TTE结合MTEE对AVP的定位、定量诊断有较高的正确性。结论 TTE和MTEE检查是早期正确诊断AVIE并发AVP的首选方法 ,有重要临床应用价值。
Objective To study the value of transthoracic echocardiography (TTE)and multiplane transesophageal echocardiography (MTEE) for detecting the aortic valvular perforation(AVP) in the aortic valvular infective endocarditis (AVIE).Methods Ten consecutive patients with AVP in AVIE were examined by TTE or/and MTEE,the features of echocardiography were compared with those of surgery.Results The echocardiographic points of AVP diagnosed by TTE or/and MTEE in the patient with AVIE were an interruption of aortic leaflet tissue continuity in the two dimensional echocardiography and a high velocity eccentric turbulent jet traversing a valve leaflet tissue in color Doppler flow imaging. The accuracy diagnosed by TTE or/and MTEE was very higher with specificity(100%) and sensitivity( 90.9 %). Conclusions TTE or/and MTEE can reliably detect AVP earlier in AVIE. MTEE is better than TTE in detecting AVP.
