In selected patients with atrial fibrillation, RFCA is a relatively effective and well-tolerated procedure to cure atrial fibrillation. Even though the results of our systematic review favour ablation therapy, large, well-designed RCTs are needed to confirm the efficacy and safety of RFCA for the management of atrial fibrillation.
The use of 3-dimensional mapping system completely avoided the use of fluoroscopy in most cases, with very low fluoroscopy time in the remaining and high safety and effectiveness profiles. Achievement of ZFL was predicted by the type of arrhythmia, operator's experience, and patient's age.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
