Primary Outcome Measures
NameTimeMethod
<p>The incidence of dormant conduction during the ablation procedure will be<br /><br>established en compared for three different ablation timeframes including 90,<br /><br>120 or 150 seconds of additional cryoballoon ablation after acute PV isolation</p><br>
Secondary Outcome Measures
NameTimeMethod
<p>1. The efficacy of AF ablation with the second-generation cryoballoon at 1 year<br /><br>follow-up will be investigated and also compared for the three different<br /><br>ablation timeframes<br /><br><br /><br>2. The incidence of (transient) phrenic nerve injury for the three groups will<br /><br>be registered and compared. The influence of the distance measured on CT scan<br /><br>between the RSPV ostium and the right phrenic nerve on the incidence will be<br /><br>assessed.<br /><br><br /><br>3. The incidence of esophageal lesions for the three groups will be established<br /><br>with gastroendoscopy and compared. The influence of minimal luminal esophageal<br /><br>temperature (LET) and cryoballoon temperature, duration of cryoenergy<br /><br>application and mean LET decrease on the formation of thermal lesions will be<br /><br>evaluated. </p><br>
