The 2 lesion sets (left atrial and BA) are associated with similar 30-day mortality, survival rates, incidences of embolic events and atrioventricular conduction disturbances. In patients with persistent atrial fibrillation, concomitant surgical ablation with BA lesion set provided better freedom from atrial arrhythmia recurrence, but BA ablation was associated with a higher incidence of sinus node dysfunction and a higher rate of pacemaker implantation.

We have not revealed significant difference in the freedom from first reintervention among types of conduit. Calcification leading to the conduit dysfunction was present in all groups; however, diepoxy-treated porcine aortic conduits demonstrated suboptimal results in terms of calcification at follow-up.
