Cryoablation vs. Anti-Arrhythmic drug therapy as a first line treatment
in Atrial fibrillation (meta-analysis and systematic review)
Abstract
Intro: Atrial fibrillation (AF) is the most frequently diagnosed
arrhythmia in practice. Current guidelines on management of AF suggest
that patients should be treated with antiarrhythmic drugs (AAD) as
first-line therapy, our meta-analysis aims to assess the benefit of
using of Cryoablation as a first line therapy for people with atrial
fibrillation. Methods: We conducted an electronic search using Medline,
Embase, CINAHL and google scholar along with other clinical trial
registries. Results: 2 studies out of 9,244 studies fit our eligibility
criteria. A total of 521 subjects were included in both studies and 4
distinct meta-analyses were performed. In terms of recurrence CA was
superior to AAD with a RR of 0.6. For serious adverse events CA was also
superior to AAD with a RR of 0.66 and for treatment related SAE the
results were insignificant. Conclusion: CA proved to be superior in
terms of recurrence and adverse effects versus AAD.
