Adverse events
A summary of adverse events from the included studies is shown in table 4. Studies reporting zero event rates in both ablation and AAM group were excluded from the meta-analysis for adverse events. As such, we performed a meta-analysis of adverse events with these available outcomes in at least two of the included studies. There were no differences in adverse events from studies in which data were available for meta-analysis for cerebrovascular accident, PV stenosis, pericardial effusion or tamponade, bradycardia requiring pacemaker, syncope, acute coronary syndrome, deep vein thrombosis (DVT) and pulmonary embolism (PE). Other adverse events that we did not perform meta-analysis included mortality, phrenic nerve injury, esophageal-related complications, and perforation.
