Predictors of ERAT after Surgical AF ablation
In our study, the occurrence of ERAT was associated with older age,
persistent AF, larger LA size, and history of CAD; these have been
identified as predictors of ERAT after catheter AF ablation.
Furthermore, longer CPB time and reoperation for bleeding probably
reflect co-morbidities and the presence of concomitant valve diseases
that further contribute to the development of ERAT. Paradoxically, ERAT
is seen more often in patients who underwent bi-atrial surgical AF
ablation. These observations suggest that bi-atrial surgical ablation
might be preferentially selected in a fragile cohort of patients with
late AF recurrence. More extensive bi-atrial ablation led to sinus node
dysfunction due to surgical damage.21 Transient
pacemaker implantation or use of inotropic agents resulted in the
development of AF in early postoperative periods.
