Pecha et al studies patients who required permanent pacemaker placement within 30 days of surgical ablation for atrial fibrillation. Pacemaker placement is a complication of surgical ablation. The authors are from the University Heart Center in Hamburg.

Patient selection: surgical ablation for atrial fibrillation


Indications for pacemaker placement:

(1) atrioventricular block

(2) sinus bradycardia

(3) sinus arrest

(4) bradyarrhythmia


Biatrial ablation is associated with a 2-fold increase in implantation rate compared to left atrial ablation alone.


A valve replacement procedure resulted in a slightly higher rate but this was not statistically significant.


Other factors (energy source, comorbid condition, demographics) appeared to influence the rate.
