多谱勒超声心动图诊断感染性心内膜炎的价值

The Diagnostic Significance of Doppler Echocardiography in Patients with Infective Endocarditis

作者对１０５例感染性心内膜炎（Ｉｎｆｅｃｔｉｖｅｅｎｄｏｃａｒｄｉｔｉｓ，ＩＥ）患者的多谱勤超声心动图（Ｄｏｐｐｌｅｒｅｃｈｏｃａｒｄｉｏｇｒａｐｈｙ，ＤＥＣ）结果与临床表现进行分析，探讨ＤＥＣ在ＩＥ诊断中的价值。结果：ＩＥ的主要病因为风心病和先心病，占７２．４％，赘生物阳性率６２．９％。有无赘生物与血培养结果、栓塞及死亡率无相关性，但有赘生物者心衰发生率高，且左心系统赘生物伴心衰者死亡率高。赘生物并瓣膜脱垂者并发症发生率高。ＤＥＣ在ＩＥ诊断中不仅提供病因病理诊断，还能对并发症的预后代判断，有较高的应用价值。

ne hundred and five patients with infective endocarditis were examined with Doppler echocardio-graphy.The result showed that most causes of the patients were with rheumatic and congenital heartdisease (72.4%).Vegetation(V)rate was 62.9%, mainly in valvular disease,The existence of V didnot predict the complications and death, but the coexistence of V and valvular prolapse significantlysuggested poor prognosis. Left valvular prolapse had high rate of heart failure and death.In addition,the morphology of V could be predictive of the prognosis and complications.
