Abstract

BACKGROUND

The clinical implications of a negative multiplane transesophageal echocardiography (TEE) have not yet been reported. We aim to determine the negative predictive value (NPV) of a negative multiplane TEE in patients with suspected infective endocarditis (IE).

METHODS AND RESULTS

We identified 83 consecutive patients with suspected IE and negative multiplane TEE from our echocardiographic database. Of 74 patients with a minimum of 1-month follow-up, only 1 patient developed "definite IE". Eight patients had "possible IE". The calculated NPV of multiplane TEE in IE was 98.6% if we only considered the case of "definite IE". If we assumed that all patients with "possible IE" had the disease, then the NPV of multiplane TEE was 87.8%.

CONCLUSIONS

Multiplane TEE is a highly accurate diagnostic tool with excellent NPV in IE. However, in a highly suspicious clinical setting for IE, a repeat TEE is still recommended to assess evolving echocardiographic features.

摘要

背景

多平面经食管超声心动图（TEE）检查结果为阴性的临床意义尚未见报道。我们旨在确定多平面TEE检查结果为阴性对疑似感染性心内膜炎（IE）患者的阴性预测值（NPV）。

方法与结果

我们从超声心动图数据库中连续筛选出83例疑似IE且多平面TEE检查结果为阴性的患者。在74例至少随访1个月的患者中，只有1例发生“确诊IE”。8例患者为“可能IE”。如果仅考虑“确诊IE”的情况，多平面TEE在IE中的计算NPV为98.6%。如果我们假设所有“可能IE”患者均患有该病，那么多平面TEE的NPV为87.8%。
