Catheter Ablation of Atrial Fibrillation [PDF]

Journal of Arrhythmia, 2007
Atrial fibrillation is the most common arrhythmia encountered in clinical practice and can result in significant morbidity and mortality. Catheter ablation has become a feasible therapeutic option for the management of this complex and challenging arrhythmia.

Catheter Ablation of Ventricular Tachycardia [PDF]

Circulation, 2010
Ventricular tachycardia (VT) most commonly develops in patients with structural heart disease. Myocardial infarction results in collagen replacement interspersed with surviving myocardium, which alters impulse propagation, facilitating re-entry.1 Aside from the postinfarction substrate, scar-mediated VT occurs in patients with nonischemic ...

Impact of undiagnosed obstructive sleep apnea on atrial fibrillation recurrence following catheter ablation (OSA-AF study)

International Journal of Cardiology: Heart & Vasculature, 2022
Background: Sleep-disordered breathing (SDB) may hamper the outcome of catheter ablation of atrial fibrillation (AF). However, SDB is underdiagnosed in clinical practice and the relevancy of undiagnosed SDB on the outcome of catheter ablation is unclear.

Pulsed field ablation prevents chronic atrial fibrotic changes and restrictive mechanics after catheter ablation for atrial fibrillation

Europace, 2021
Aims Pulsed field ablation (PFA), a non-thermal ablative modality, may show different effects on the myocardial tissue compared to thermal ablation. Thus, this study aimed to compare the left atrial (LA) structural and mechanical characteristics after ...

Catheter Ablation for Ventricular Tachycardia [PDF]

Circulation, 2004
Sustained ventricular tachycardia (VT) is an important cause of morbidity and sudden death in patients with heart disease.1 Implantable cardioverter-defibrillators (ICDs) terminate VT episodes, reducing the risk of sudden death. Recurrent VT develops in 40% to 60% of patients who receive an ICD after an episode of spontaneous sustained VT.

Pulmonary veins isolation using cryoballoon and pulsed field ablation for atrial fibrillation: practical techniques in variable scenarios

International Journal of Arrhythmia, 2023
Catheter ablation is the most effective treatment for atrial fibrillation (AF). Electrical pulmonary veins isolation (PVI) forms the cornerstone ablation strategy.

Catheter Ablation for the Management of Atrial Fibrillation: An Update of the Literature

Life, 2023
Catheter ablation has been shown to be more effective at maintaining sinus rhythm and improving quality of life when compared to antiarrhythmic drugs. Radiofrequency and cryoablation are two effective methods.

Effect of Catheter Ablation With Vein of Marshall Ethanol Infusion vs Catheter Ablation Alone on Persistent Atrial Fibrillation: The VENUS Randomized Clinical Trial.

Journal of the American Medical Association (JAMA), 2020
Importance Catheter ablation of persistent atrial fibrillation (AF) has limited success. Procedural strategies beyond pulmonary vein isolation have failed to consistently improve results. The vein of Marshall contains innervation and AF triggers that can

Advanced ablation strategies for management of post-surgical atrial arrhythmias. [PDF]

, 2013
Post-surgical arrhythmias include a wide range of arrhythmias occurring late after cardiac surgery and represent a complex substrate for catheter ablation either because of extended scar and remodeling or because of limited access to the area of interest.

Effect of Renal Denervation and Catheter Ablation vs Catheter Ablation Alone on Atrial Fibrillation Recurrence Among Patients With Paroxysmal Atrial Fibrillation and Hypertension: The ERADICATE-AF Randomized Clinical Trial.

Journal of the American Medical Association (JAMA), 2020
Importance Renal denervation can reduce cardiac sympathetic activity that may result in an antiarrhythmic effect on atrial fibrillation. Objective To determine whether renal denervation when added to pulmonary vein isolation enhances long-term ...
