Abstract

In expectation of better outcome of catheter ablation of atrial fibrillation (AF), several strategies of extra-PV (pulmonary vein) substrate modification have been utilized. We assessed whether substrate modification or ablation of extra-PV source is a predictor of complications. Japanese Heart Rhythm Society requested electrophysiology centers to register the data of patients who underwent AF ablation. The data of 10 795 AF ablation cases (age; 63.8 ± 10.6 years) treated during 2011-2016 were registered. Pericardial effusion (n = 105), massive bleeding (n = 108), stroke (n = 6), atrial-esophageal fistula (n = 2), and other 114 complications occurred in 323 patients (3.0%). Univariate analysis revealed that age ≧ 65 years, female gender, heart failure, CHA2DS2-VASc≧3, hemodialysis, deep sedation, and complex fractionated atrial electrogram (CFAE)-guided ablation ([+] vs [-] = 4.3% vs 2.8%, P = .005) were related with the higher incidence of complications. Redo session, 3-D imaging system ([+] vs [-]: 4.4% vs 2.9%, P = .017), and periprocedural dabigatran were related with the lower incidence of complications. None of the linear ablation of the left atrium, ganglionated plexi ablation, and superior vena cava ablation affected th...Continue Reading

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
