Brief summary

Atrial fibrillation is a common heart rhythm disorder and is associated with heart rhythm irregularity. This trial aims to compare the relative efficacy of 2 different keyhole procedures to cure atrial fibrillation.

Interventions

Pulmonary vein isolation by wide encircling ablation of ipsilateral veins with linear ablation of the intervenous ridge. This procedure takes 2-4 hours and involves advancing specialized catheters into the heart via a keyhole approach, and using heat energy to place strategically-positioned scars in the upper chambers of the heart to cure atrial fibrillation. It is done as a one-off procedure, though occassionally a second procedure is required.
