Persistent atrial fibrillation vs paroxysmal atrial fibrillation: differences in management

Expert Review of Cardiovascular Therapy, 2017
Atrial fibrillation (AF) is the most common human arrhythmia. AF is a progressive disease, initially being nonsustained and induced by trigger activity, and progressing towards persistent AF through alteration of the atrial myocardial substrate.

Pulsed Field or Conventional Thermal Ablation for Paroxysmal Atrial Fibrillation.

New England Journal of Medicine, 2023
BACKGROUND Catheter-based pulmonary vein isolation is an effective treatment for paroxysmal atrial fibrillation. Pulsed field ablation, which delivers microsecond high-voltage electrical fields, may limit damage to tissues outside the myocardium.

Catheter ablation as first-line treatment for paroxysmal atrial fibrillation: a systematic review and meta-analysis

Heart, 2021
Objective To assess the efficacy and safety of catheter ablation (CA) compared with antiarrhythmic drugs (AADs) as first-line treatment for symptomatic paroxysmal atrial fibrillation (AF).

Predictors of clinical success after paroxysmal atrial fibrillation catheter ablation

Cardiovascular Electrophysiology, 2021
Contact force (CF) guided ablation of paroxysmal atrial fibrillation (PAF) with stable catheter‐tissue contact optimizes clinical success and may increase an operator's ability to achieve pulmonary vein isolation (PVI) in a single encirclement.

[PAROXYSMAL ATRIAL FIBRILLATION].

Bollettino della Societa italiana di cardiologia, 1996
Paroxysmal atrial fibrillation is an extremely common form of atrial fibrillation seen by most physicians. Despite making up more than 40% of the cases of atrial fibrillation, its management continues to be neglected in the medical literature. Many of the recent large-scale prospective trials have excluded these patients.

Left atrial vortex size and velocity distributions by 4D flow MRI in patients with paroxysmal atrial fibrillation: Associations with age and CHA2DS2‐VASc risk score

Journal of Magnetic Resonance Imaging, 2020
Characterization of left atrial (LA) hemodynamics in paroxysmal atrial fibrillation (PAF) may provide valuable insights for thromboembolic risk.

Comparison of myocardial injury and inflammation after pulmonary vein isolation for paroxysmal atrial fibrillation between radiofrequency catheter ablation and cryoballoon ablation

Cardiovascular Electrophysiology, 2020
Several studies have shown the serum high sensitive cardiac troponin I (hs‐TnI) a biomarker of myocardium injury, and C‐reactive protein (CRP), a biomarker of inflammation, are associated with worse cardiovascular outcomes.

Safety and outcome of very high-power short-duration ablation using 70 W for pulmonary vein isolation in patients with paroxysmal atrial fibrillation.

Europace, 2019
AIMS Pulmonary vein isolation (PVI) using radiofrequency ablation (RFA) in patients with paroxysmal atrial fibrillation (PAF) is effective but hampered by pulmonary vein reconnection due to insufficient ablation lesions.

Propafenone for paroxysmal atrial fibrillation

The American Journal of Cardiology, 1988
Abstract Propafenone is a class 1C antiarrhythmic agent potentially effective in paroxysmal atrial fibrillation (AF). Propafenone's effects upon automaticity and conduction in the atrium should decrease the frequency of AF. In the event of a recurrence of AF, its effects on atrioventricular nodal conduction would tend to slow the ventricular response.

Pulsed Field or Cryoballoon Ablation for Paroxysmal Atrial Fibrillation.

New England Journal of Medicine
BACKGROUND Pulmonary-vein isolation is an effective treatment for paroxysmal atrial fibrillation. Pulsed field ablation (PFA) is a nonthermal ablation method with few adverse effects beyond the myocardium.
