The results came as a shock to many: the rate of overall complications from left atrial ablation (ie, pulmonary vein isolation/AF ablation) was 11.7% to 13.5% with a major complication rate of 3.8% to 7.2%. Note that most of the complications were nonmajor complications. Pericardial effusion occurred in 3.5%, pneumonia in 0.8%, stroke in 0.6%, and AV block III° in 0.3%. Individual complications were as follows: an average of 7.1% for access site complications defined as bleeding, hematoma, shock, infection, and vascular complications. Complication rates were related to location of ablation and type of energy used. The analysis used ICD-10, DRG, and OPS codes to study 33 353 German cases of catheter ablation for AF and atrial flutter in 2014. This was the conclusion of a recent German analysis, presented at the European Society of Cardiology Scientific Congress 2018 and published in the European Heart Journal.

However, as our knowledge of (and expertise with) ablation evolve, we are appreciating that even procedures once perceived as relatively safe (based on analyses from retrospective studies and clinical trial data) carry significant complication rates when analyzed in a “real world” setting. With the recent publication of the CABANA trial results, there has been a lot of enthusiasm for offering ablation as a first-line therapy for atrial fibrillation (AF).
