title: [Transesophageal echocardiography--a method for prompt diagnosis of acute hemodynamically significant pulmonary embolism].
abstract: Patients with acute pulmonary embolism (PE) may require prompt confirmation of PE before aggressive therapy such as embolectomy or thrombolysis. However, emergency availability of routine diagnostic tests often remains a problem. Therefore, we assessed prospectively the diagnostic value of transesophageal echocardiography (TEE), recently reported to be useful in the diagnosis of PE. TEE was performed in 76 consecutive patients (42 F, 34 M) aged 66.7 +/- 15.8 yrs with suspected acute PE with echocardiographic signs of right ventricular pressure overload, but without known coexisting cardiorespiratory diseases. Pulmonary artery thrombi (TH) were visualized at TEE in 69.7% (53) pts. PE was confirmed by high probability lung scintigraphy and/or spiral CT in all these cases. Additionally, PE was diagnosed in 11 others without TEE-reported TH. In the 12 remaining patients PE was eventually excluded (specificity 100%, sensitivity 82.8%). Therefore, TEE in the diagnosis of hemodynamically significant PE reached 100%. No clinically important adverse events were observed during TEE.
  
  
  CONCLUSIONS
  Transesophageal echocardiography is reliable and safe method of prompt confirmation of hemodynamically significant acute pulmonary embolism with relatively high sensitivity in adequately preselected patients. However, due to topographic limitations negative result of TEE does not exclude PE.
