Abstract

Introduction: A growing body of evidence suggests a strong association between atrial fibrillation (AF) and cancer. A relevant number of patients with a present or former malignant disease with highly symptomatic drug-refractory AF are in need of interventional therapy. Data on the safety and efficacy of catheter ablation in these patients are sparse. The present study aims to analyze the safety and efficacy of cryoballoon-based pulmonary vein isolation (CB-PVI) for symptomatic AF in patients with past or present cancer disease. Methods and Results: Consecutive patients undergoing CB-PVI for symptomatic AF at University Hospital Lübeck, Germany between July 2015 and January 2019 were included in this study. Propensity-score based matching was performed to identify comparable patients with and without cancer disease and further analyze clinical characteristics, periprocedural complications and arrhythmia-free survival. A total of 70 patients with a history of cancer undergoing CB-PVI were matched to 70 patients without a history of cancer. The frequency of complications was similar between patients with and without a history of cancer (p = 0.11), with four phrenic nerve palsies occurring in patients with a history of cancer (5.6% of the cohort) vs. one phrenic nerve palsy in patients without cancer (p = 0.36). Arrhythmia free survival after 12 months did not differ significantly in patients with and without a history of cancer (67.1 ± 5.8% vs. 77.8% ± 5.1%, p = 0.16). Conclusion: This study indicates that CB-PVI for symptomatic AF is equally safe and effective in patients with and without a history of cancer and cancer treatment.
