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.
