Changes in mitral annular velocities after cardioversion of atrial fibrillation

Abstract

We demonstrated that e' was significantly higher in AF compared with during sinus rhythm in the same patients. Thus, in AF patients, diastolic dysfunction should be suspected even when e' values are normal.

<p>The Predictive Value of Tissue Doppler Indices for Early Recurrence of Atrial Fibrillation After Electrical Cardioversion</p>

“…In our study, septal, lateral, and average e' decreased, whereas E/e' increased, but the change remained statistically insignificant. This result is similar to the findings of Park et al, 12 where e' was significantly higher in AF compared with during SR in the same patients. Restoration of atrial mechanical contraction following ECV improved LV systolic function, assessed by s', and together had a larger impact on LV function assessed by E/(e'xs') ratio that statistically significantly improved.…”

“…[5][6][7][8][9][10] A comprehensive systematic review by D. Kotecha reported that diastolic function indices, particularly E/e', are valid and reproducible in patients with AF when the appropriate cardiac cycles are carefully selected. 11 Nevertheless, Park et al 12 revealed in their small study that E/e′ was significantly lower in AF compared with SR during 1 month after ECV in the same patients. There is limited data demonstrating how e' changes after SR restoration in AF patients and this information is useful to confirm E/e' ratio constancy in AF patients.…”

“…1 The ratio of mitral peak early diastolic filling velocity (E) to peak early diastolic mitral annular velocity (e') estimated by Doppler tissue imaging (E/e') is one of the four main echocardiographic variables for diagnosing a diastolic dysfunction. 2,3 In recent studies, a new Doppler index -the ratio of E to e' multiplied by peak systolic mitral annular velocity (s') derived by Doppler tissue imaging (E/(e'xs'), is demonstrated to be superior to E/ e', e', s', or E in sinus rhythm (SR) patients and has high diagnostic accuracy, particularly in patients with intermediate values for E/e' ratio (8)(9)(10)(11)(12)(13)(14)(15). 4 Elevated E/e' ratio and to a lesser extent E/(e'xs') have been confirmed as beneficial predictors of new-onset AF, AF recurrence after electrical cardioversion (ECV), and worse outcomes in patients with various heart diseases.…”

Significance of mitral L‐waves in predicting late recurrences of atrial fibrillation after radiofrequency catheter ablation

“…Park et al. reported that the e' values during AF were significantly higher than that during sinus rhythm in the same patients receiving electrical cardioversion to restore sinus rhythm 23 . Thus, the E/e' values during AF were expected to be inappropriately lower than that during sinus rhythm.…”

“…In this study, some patients received transthoracic echocardiography during AF. procedure could cause unreliable results for estimating the LVDD in AF patients.Park et al reported that the e' values during AF were significantly higher than that during sinus rhythm in the same patients receiving electrical cardioversion to restore sinus rhythm 23. Thus, the E/e' values during AF were expected to be inappropriately lower than that during sinus rhythm.…”
