Condensed abstract
Catheter ablation is an established, effective approach for the
treatment of AF in patients with heart failure, however the role of
cryoablation in this setting is unclear. Procedural success and LVEF
improvement in patients with LVEF≤45% undergoing index catheter
ablation with cryoablation were evaluated. Freedom from AF recurrence
was seen in 43% rising to 59% following repeat procedure. There were
significant improvements in LVEF and functional status at long-term
follow up. Cryoablation is an effective first-line AF ablation approach
in the setting of heart failure.
