Randomized Controlled Trial Multicenter Study Comparative Study
Rationale and design of AXAFA-AFNET 5: an investigator-initiated, randomized, open, blinded outcome assessment, multi-centre trial to comparing continuous apixaban to vitamin K antagonists in patients undergoing atrial fibrillation catheter ablation.
Catheter ablation is the most efficacious rhythm control therapy in atrial fibrillation (AF) patients. There is growing evidence that catheter ablation procedures are best performed during continuous oral anticoagulation, but outcomes are variable depending on the anticoagulation strategy or agent chosen. Specifically, there is a need to evaluate the peri-procedural use of non-vitamin K antagonist oral anticoagulants (NOACs) in patients undergoing catheter ablation of AF. The AXAFA-AFNET 5 trial will test whether peri-procedural anticoagulation therapy using apixaban is a safe alternative to vitamin K antagonist (VKA) therapy for patients undergoing catheter ablation of AF. ⋯ The results of AXAFA-AFNET 5 will provide evidence informing about the safety of apixaban in ablation patients and on its efficacy including effects on silent brain lesions. AXAFA - AFNET 5 is an investigator-initiated trial sponsored by AFNET. The trial is supported by the DZHK (German Centre for Cardiovascular Research) and by the BMBF (German Ministry of Education and Research) and by Bristol-Myers Squibb/Pfizer Alliance.

Multicenter Study Comparative Study
Results from a multicentre comparison of cryoballoon vs. radiofrequency ablation for paroxysmal atrial fibrillation: is cryoablation more reproducible?
Cryoballoon ablation (Cryoballoon) has emerged as a new alternative for the treatment of symptomatic drug-refractory atrial fibrillation (AF). Whether the results of Cryoballoon are more reproducible than those of radiofrequency (RF) ablation remains to be proved. ⋯ Cryoballoon seems to be less operator-dependent and more reproducible than RF in the setting of paroxysmal AF ablation.
