Will simultaneous measurement of E/e' index facilitate the non-invasive assessment of left ventricular filling pressure in patients with non-valvular atrial fibrillation?
Abstract
AIMS: The ratio of early transmitral flow velocity (E) to early diastolic mitral annular velocity (e') was applied as a non-invasive index to assess left ventricular filling pressure (LVFP). However, the reliability of E/e' was undermined in patients with atrial fibrillation (AF). Recently, a novel method entitled 'dual Doppler' was established, which allows simultaneous recording and display of E and e'. Our study investigates whether the dual-Doppler method improves the reliability of E/e' in AF patients. METHODS AND RESULTS: Forty-nine patients with non-valvular AF underwent conventional echocardiography, dual-Doppler echocardiography, and cardiac catheterization within 4 h. Of 22 patients (45%c) with increased LVFP (>15 mmHg), higher E/e' measured by both conventional tissue Doppler imaging (TDI) and dual-Doppler method was observed. Conventional echocardiographic variables were correlated with LVFP (E/e'(sep), r = 0.404, E/e'(lat), r = 0.487), but E/e' measured synchronously in the dual-Doppler mode yielded a better correlation (E/e'(synchronous sep), r = 0.754, E/e'(synchronous lat), r = 0.765). The intra- and interobserver variability of the dual-Doppler method was significantly lower than the conventional TDI method. CONCLUSION: Good correlations were found between E/e'' and LVFP in patients with AF, particularly in the dual-Doppler mode. E/e' measured by the dual-Doppler method can therefore be applied to assess diastolic dysfunction in AF patients.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
