Anesthesiologists using TEE provide information equivalent to that provided by any consulting physician (e.g., cardiologist) using echocardiography for a given indication. This is not part of, but rather in addition to, the anesthesia service being provided.
Anestesiologistas que usam ETE fornecem informações equivalentes às fornecidas por qualquer médico consultor (por exemplo, cardiologista) usando ecocardiografia para uma determinada indicação. Isso não faz parte, mas sim adiciona, além do serviço de anestesia fornecido.
Impact of Diastolic Function Parameters on the Risk for Left Atrial Appendage Thrombus in Patients with Nonvalvular Atrial Fibrillation: A Prospective Study
This prospective and concomitant evaluation of diastolic function and LAA thrombus in patients with NVAF demonstrates that E/e′ ratio and e′ velocity are associated with LAA thrombus, independent of CHA2DS2-VASc score, and may play a role in identifying patients at low risk for LAA thrombus. These data suggest that diastolic function assessment may improve stroke prediction in patients with NVAF.
Interessante uso da relação E/e´na fibrilação atrial.

A FAC já é uma disfunção importante quando perde a organização do ritmo sinusal.
Disease prevalence of our cohort was 29.4%. The area under the curve for the classification result on validation set was 0.87, and the average analysis time was 10 ± 3 ms per subject. Sensitivity, specificity and accuracy were 88.9%, 73.3% and 77.8%, respectively.
Cardiac stroke volume can be estimated by multiplying the velocity-time integral obtained from Doppler examination of the LV outflow tract by the LV outflow tract area . Doppler examination requires parallel alignment of the pulse-wave beam with the LV outflow tract. Nonparallel beam alignment can result in a reduced LV stroke volume by underestimating the velocity-time integral. Furthermore, this method requires accurate estimation of the LV outflow tract diameter; minor inaccuracies in diameter estimation result in marked errors in the area calculation because of the squaring of the radius.
Mas padece dos mesmos vícios que a estimativa de área valvar na estenose aórtica.
Assessment of LV function remains the most common reason for cardiac imaging because of its powerful ability to predict morbidity and mortality. Current routine methods of quantifying LV function (with LVEF) is not without limitations. Strain imaging that uses speckle tracking in 2-D and 3-D offers promise for quantifying LV function, particularly for patients with borderline LV function, because of the potential to identify subclinical disease. Strain imaging offers the treating physician a unique opportunity to alter management before the onset of overt LV dysfunction, which may, in turn, improve prognosis.
