Impact of asymmetrical dilatation of the left atrium on the long-term success after catheter ablation of atrial fibrillation

Prognostic implication of left atrial sphericity in atrial fibrillation patients undergoing radiofrequency catheter ablation

“…Our data suggest that LA sphericity influenced by mLAP precedes a severe LA enlargement in nonvalvular AF patients with preserved LV systolic function, and LA sphericity is an early marker—before overt chamber dilation—for future AF/AT recurrences after RFCA. Of note, LA volume in this research is larger than the data from the study performed by Bisbal et al., but similar to other data including ours; probably different patient selection strategy among researcher groups might explain the discrepancy.…”

“…Although the precise mechanism for the failure to maintain sinus rhythm is unclear, numerous predictors for outcomes after RFCA have been suggested . The concept of atrial shape changes is a recently introduced predictor for AF recurrence after RFCA . In a study performed with AF patients undergoing RFCA, Bisbal et al .…”

Association between peripheral plasma markers and left atrial anatomy in patients with atrial fibrillation

“…This provided new insights on the LA shape and volume, which have been proven to be better predictors of AF recurrences after LA ablation in comparison to the commonly used anterior-posterior LA diameter [4][5][6]. Recently we demonstrated that LA dilatation is more pronounced on the coronal plane, as represented by the transversal LA diameter (LA-TV) [7].…”

“…There are several imaging modalities to assess the LA, though echocardiography is widely available and thus the most frequently used. However, the echocardiographic LA diameter (LA-D) does not reliably reflect the true size of LA anatomy, as pathological LA is often enlarged asymmetrically during AF progression [4][5][6].Computer tomography (CT) is a modality that has been increasingly used to obtain three-dimensional (3D) images prior to AF catheter ablation. This provided new insights on the LA shape and volume, which have been proven to be better predictors of AF recurrences after LA ablation in comparison to the commonly used anterior-posterior LA diameter [4][5][6].…”
