摘要
目的 探讨经胸二维超声心动图 (2DE)和彩色多普勒血流显像 (CDFI)诊断感染性心内膜炎(IE)伴主动脉瓣穿孔(AVP)的价值。方法 分析和总结11例经2DE及CDFI诊断的IE并AVP患者的经胸超声心动图(UCG)资料 ,将其UCG特点与手术结果进行对照。结果 在胸骨旁、心尖左室长轴切面及心底短轴切面 :2DE显示瓣体回声缺失 ,CDFI显示瓣体回声缺失部位有穿瓣偏心血流 ;UCG诊断IE并AVP特异性、敏感性均为90.9% ;瓣膜实际穿孔口大小明显>2DE测量值 ;AVP是IE较常见的并发症 ,IE穿孔的瓣膜中以主动脉瓣最为常见。结论 UCG检查是早期正确诊断IE并AVP的首选方法 ,但对AV多瓣叶的穿孔、瓣周脓肿。
Objective To discuss the value of 2-dimential echocardiogram (2DE) and color doppler flow imaging (CDFI) on diagnosing aortic valve infective endocarditis (AVIE) accompanied with aortic valve perforation (AVP). Methods The echocardiogram characteristic of AVIE accompanied with AVP (11 cases) was analyzed and compared with the operation results. Results The echocardiogram characteristics were as following: interrupt and disappearance of valve echo in transthoracic echocardiogram (TTE), and trans-valve eccentric flow the non-echo part in CDFI. The specificity is 100% and the sensitivity is 90.9%. The TTE had some limit on diagnosing multi-valve perforation, circumjacent abscess of aortic valve and pulmonic valve perforation. Conclusion Echocardiogram examination was an optimal method to diagnose AVIE accompanied with AVP. In some cases, MTEE examination could make up the shortage of TTE.
