Outcome Measures

Primary Outcomes (1)

  • Comparison of successful catheter ablation between both methods.

    Successful ablation will be defined as absence of clinical VA or \> 50% reduction in arrhythmia burden on Holter in the absence of anti-arrhythmic medication.

    During procedure and 1 month follow up

Secondary Outcomes (2)

  • Comparison of complications such as pericardial effusion/ tamponade, coronary artery damage and post procedure pericardial pain requiring medical management.

    During Procedure

  • Comparison of procedure and fluoroscopy time between both strategies

    During Procedure

Model Details: Group sample sizes of 44 in Group 1 and 44 in Group 2 achieve 80% power to detect a difference between the group proportions of -0.2000. The proportion in Group 1 (the treatment group) is assumed to be 0.2500 under the null hypothesis and 0.0500 under the alternative hypothesis. The proportion in Group 2 (the control group) is 0.2500. The test statistic used is the two-sided Z test with pooled variance. The significance level of the test was targeted at 0.0500. The significance level actually achieved by this design is 0.0531.
