Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Incidence of phrenic nerve palsy [ Time Frame: 06/2012 until 04/2018 ]
    The overall incidence of phrenic nerve palsy during second and third Generation Cryoballoon based PVI will be evaluated.


Secondary Outcome Measures :
  1. Predictors of phrenic nerve palsy [ Time Frame: 06/2012 until 04/2018 ]
    Predictors for transient and permanent phrenic nerve palsy will be evaluated. For this purpose baseline characteristics (e.g. age, sex, BMI, CHADS-VASc-Score) as well as periprocedural data (e.g. minimal cryoballoon temp., cryoballoon temp. after 30 seconds, time to isolation, PV diameter, use of doublestopp technique and draw back manouever) will be assesseda and predictors will be calculated using adequat statistical techniques.

  2. Clinical course of phrenic nerve palsy [ Time Frame: 06/2012 until 04/2018 ]
    The clincial course of phrenic nerve palsy after second and third Generation Cryoballoon based PVI will be evaluated by follow-up appointments according to each centers standard of care. For this purpose follow-up data will be evaluated and the clinical course will be assessed.
