Introduction: Atrial arrhythmias (AA) are common after lung transplant (LT) and may impact overall mortality. The majority of arrhythmias tend to be organized flutter, amenable to ablation; however the data is limited. Hypothesis: The purpose of this study was to investigate the outcomes of radiofrequency catheter ablation of AA in LT recipients. Methods: All LT recipients undergoing electrophysiology study at our institution between 2011-2018 were retrospectively reviewed. A total of 20 atrial ablations were identified in 16 patients. Mean follow-up was 4 ± 2.9 years. Results: Overall, mean age was 55 ± 13 years, 63% were male, 63% were status post bilateral (vs. single) LT, and mean LVEF was 57%. Transplant indications included interstitial lung disease (44%), COPD (19%), and cystic fibrosis (19%). Antiarrhythmics and beta blockers were used in 44% and 75%, respectively. Mean time from transplant to first ablation was 2.7 years. Of 20 ablations, macro-reentrant flutter (75%) and focal atrial tachycardia (15%) were common, particularly in double LT recipients (Figure). The most common ablation sites were pulmonary vein anastomosis/left atrial ridge (60%), mitral annulus (35%) and left atrial roof (30%). Restoration of sinus rhythm occurred in 19 of 20 procedures and only one complication occurred (e.g. small pericardial effusion without tamponade). Arrhythmia recurred in 10 (63%) patients, however, most were managed conservatively. Repeat ablation was needed in 4 patients, of which AAs originated from different locations. Beta blocker use was associated with a lower risk of SVT recurrence (p=0.04). Reduced LVEF and longer time to procedure post-transplant were associated with repeat ablation (p<0.05). Conclusions: The majority of AAs in LT recipients are atrial flutter originating near the pulmonary vein anastomosis sites. Despite a high immediate procedural success rate, recurrence is high and 25% of patients require multiple ablation attempts.
