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.
