An interventional study of Cryoballoon and Radiofrequency Energy(Contact Force) in Persistent Atrial Fibrillation, sponsored by China Cardiometabolic Registries. Status unknown at 1 site in China. Open to participants aged 18 Years to 75 Years. Per ClinicalTrials.gov, last updated 2017-02-15.
Sponsored by China Cardiometabolic Registries · Not applicable, Interventional, and Treatment
The purpose of this study is to perform a prospective, randomised study investigating the safety and efficacy of cryoballoon catheter ablation compared with radiofrequency ablation(contact force), in the treatment of persistent AF.
The hypotheses for this study is that cryothermal energy is as effective and safe as using radiofrequency energy in the treatment of persistent AF and is associated with a better long term outcome.
