Conclusions
The incidence of LA thrombi at repeat ablation for AF was quite low, with fewer imaging examinations being performed at earlier repeat ablation periods. Several significant factors, including later repeat ablation, low LVEF, and non-paroxysmal atrial arrhythmia at repeat ablation, were associated with the risk of developing LA thrombi. Our findings could provide guidance to the clinical decision on whether TEE and CT imaging should be planned before repeat ablation in reasonable patients and could suggest the usefulness of risk stratification to avoid unnecessary screening examinations in certain low-risk populations.
