SECONDARY outcome

Timeframe: Day 0

Acute procedural success is defined as the successful ablation of at least three of four pulmonary veins as shown by pulmonary vein entrance block per vein during the initial ablation procedure. A subject is considered to be an acute procedural failure if acute procedural success cannot be obtained by using the Hansen system and, as a result, manual manipulation is needed to complete the ablation procedure with the ablation catheter.

SECONDARY outcome

Timeframe: 8 - 365 days post-procedure

Chronic safety is defined as the incidence of Major Complications during the period from 8 - 365 days following the initial ablation procedure (excluding pulmonary vein stenosis and atrio-esophageal fistula from 8 - 180 days, which are included in the primary safety endpoint). The incidence of pulmonary vein stenosis and atrioesophageal fistula is included during the period from 181 - 365 days.
